If the error in the angle is 0.50, the error in sin 90° is
The error in the measurement of sin 90 degrees at the given error in angle is 0.001.
Error in measurementThe error in measurement is obtained from the difference between the actual measurement and the observed measurement.
The error of sin 90 degrees is calculated as follows;
Actual measurement = sin 90 = 1
Observed measurement = sin(90 - 0.5)
Observed measurement = sin(89.5) = 0.999
Error in measurement of sin 90 degreesError in measurement = Actual measurement - Observed measurement Error in measurement = 1 - 0.999
Error in measurement = 0.001
Thus, the error in the measurement of sin 90 degrees at the given error in angle is 0.001.

What is TRUE about the use of drawings at a crime scene?
O A. Drawings are no longer used because photography is more precise.
OB. Only when a camera is not immediately available should a sketch be made.
O c.
It is common practice for investigators to make a sketch of a crime scene.
OD. Investigators are trained in how to make a quality finished sketch of a scene.
Answer:
A. Drawings are no longer used because photography is more precise.
Explanation:
It is common practice for investigators to make a sketch of a crime scene.
Creating sketches of crime scenes is a common practice among investigators, as it provides valuable visual documentation that complements photographs and written notes. While photography is an important tool for capturing detailed and precise information, sketches offer unique advantages that contribute to the overall understanding of the crime scene.
Sketches can provide a clear and organized representation of the spatial relationships, distances, and dimensions within the crime scene. They can accurately depict the layout of the area, the position of evidence, the location of key objects, and other relevant details that may not be fully captured by photographs alone.
Additionally, sketches allow investigators to emphasize specific features or elements that are essential to the case. This can aid in explaining the sequence of events, the movement of individuals or objects, and other dynamic aspects of the crime scene.
While digital photography is widely used today, sketches remain valuable for scenarios where a camera may not immediately be available, when capturing certain angles or perspectives is challenging, or when highlighting specific details is necessary.
Investigators are trained in creating accurate and detailed sketches that adhere to professional standards. This includes ensuring accurate measurements, using appropriate scale ratios, labeling key features, and maintaining object proportions. Sketched crime scene diagrams are often included in official investigative reports and court proceedings to provide a comprehensive visual representation of the crime scene, enhancing the communication of information among investigators, legal professionals, and jurors.

to find:the resistance.
solution:Specific resistance of copper:
ρ=1.72×10^−8
Area of cross-section:
A=π×r2=3.14×10^−6 m^2
Let the resistance be R.

A car with a mass of 1500 kg is traveling at a speed of 30 m/s what force must be applied to stop the car in 3 seconds
Answer:
15 000 N
Explanation:
Newtons Law 2. When a body is acted upon by a force, the time rate of change of its momentum equals the force.
F=ma
a=30m/s / 3s=10m/c²
F=1500kg*10m/c²=15 000 N
1. What conclusions can you draw about how the sum of forces acting on an object affect its motion?
Answer:
The sum of all the forces acting on an object is the net force or resultant force. If all the forces cancel out, the resultant force is zero, else, the unbalanced force will cause acceleration of the object. Force is a vector and hence has both a direction and magnitude. For example, gravitational force (on earth) acts in downward direction and has a magnitude equal to mass of the object and acceleration due to gravity. Once we know all the forces that are acting on a body, we resolve all of them into components (typically horizontal and vertical) and take summation of forces in each direction. If such forces cancel out (in each direction), the object maintains its state of rest or constant motion. If however, forces do not cancel out, there is a net resultant force on the object that will cause acceleration of the object (as given by Newton's second law of motion).

What is DNA ?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the origin, functioning, development, and reproduction of all known organisms and viruses. DNA and ribonucleic acid (RNA) are examples of nucleic acids. Nucleic acids, together with proteins, lipids, and complex carbohydrates (polysaccharides), are one of the four basic macromolecule groups necessary for all known forms of life.
Because they are made up of simpler monomeric units called nucleotides, the two DNA strands are known as polynucleotides. Each nucleotide is made up of one of four nitrogen-containing nucleobases (cytosine, guanine [G], adenine [A], or thymine [T]), deoxyribose, and a phosphate group. Covalent bonds link the nucleotides together to form a chain.

Answer:
yes.
Explanation:
Friction exists in space, just that not in the most familiar cases. Walking or rolling are not normally possible without gravity pushing both bodies in contact with a normal force. However the normal force does not have to be only gravity, it could be caused by pressure or some other force (thrusters, magnetism etc).

A 2510 kg car, moving at 23.0 m/s, runs into a car that has a mass of 1750 kg
and is moving at 12.3 m/s in the same direction. The cars stick together after
the collision. Assuming momentum is conserved, what is their final velocity?
A. 18.6 m/s
B. 16.4 m/s
C. 19.3 m/s
D. 21.1 m/s
By conservation of momentum,
(2510 kg) (23.0 m/s) + (1750 kg) (12.3 m/s) = (4260 kg) v
where v is the velocity of the combined cars.
Solve for v :
(4260 kg) v = 79 255 kg•m/s
v ≈ 18.6 m/s
Astronomers classify galaxies into three basic types: spiral, elliptical, and irregular. If the Sun and Earth were located on the edge of an elliptical galaxy, what would you expect to see when you look up in the sky at night
Most of the night sky would be dark with only a few stars if the solar system were moved on the edge of galaxy.
What we can see at night if sun and earth moved to the edge?If the Sun and Earth were moved on the edge of an elliptical galaxy, we can see most of dark and few stars in the sky at night because stars are present at large number at the center of galaxy and fewer at th edges.

Explanation:
40208000000000 km / 28000 km/hr =
The Space shuttle's speed is 28,000 km/hr, and the time it will take to get you there is 1436000000 hours or 163814.7 years.
What is Proxima Centauri?Although Proxima Centauri cannot be seen normally with eyes, it is one of the most famous stars in the sky. This is because it is a member of the Alpha Centauri star system, which is the nearest stellar system to our sun and is home to three known stars.
Proxima, with a distance of 4.22 light-years from our sun, is thought to be the star in Alpha Centauri that is nearest to our sun of the three. For Proxima, astronomers have so far found two planets. It also produces large solar flares, and a strange radio signal may come from it.
According to the question :
The given distance is 4.3 light-years or,
Distance = 40,208,000,000,000 km
Given speed is 28,000 km/hr.
So the time it will take to get you up there is: Distance/speed
Time = 40,208,000,000,000 km/28,000 km/hr
Time = 1436000000 hours or,
Time = 163814.7 years
Hence, the time taken to get you there will be 163814.7 years.

1. A large positive charge is placed very far away from a small negative charge. Which of the best explains the interaction between the two charges?
(Standard SPS10 c)
A. An attractive, weak force
B. A repulsion, strong force
C. A repulsive, weak force
D. An attractive, large force
Answer:
A. An attractive, weak force
Explanation:
I got it right
An attractive, weak force best explains the interaction between the two charges. The force between two charges is known as the Columb's force.
What is the charge?When the matter is put in an electromagnetic field, it has an electric charge, which causes it to experience a force. A positive or negative electric charge can exist.
Charges that are similar repel each other, whereas charges that are dissimilar attract each other. The term "neutral" refers to an item that has no net charge.
A large positive charge is placed very far away from a small negative charge. Due to the far distance, the force will be a weak force.
While due to the opposite polarity the charge is attractive in nature.
Hence an attractive, weak force best explains the interaction between the two charges
