Answer:

The change in momentum for the bug and the car will be equal, impulses will be equal in opposite directions and the bug will have a greater acceleration compared to the car, because it has a smaller mass.

Answer:

Distance, d = 0.1 m

It is given that,

Initial velocity of meson,

Finally, the meson is coming to rest v = 0

Acceleration of the meson,  (opposite to initial velocity)

Using third equation of motion as :

s is the distance the meson travelled before coming to rest.

So,

s = 0.1 m

The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.  

The physical evidence are the silent witnesses against the perpetrators of a crime

The correct option of what the field inspector packages after the crime scene has been photographed is the option;

Reason:

Physical evidence are evidence that originate from inanimate objects or origin that is nonliving, and includes every material or object that serve as an indicator that someone has committed a crime, or that can link a perpetrator to crime

Examples include; Documents, hair, skin, fingerprints, weapons, soil, or fibers

The field inspector, collects the evidence that shows that a crime has been committed which are the physical evidence, after the crime scene has been photographed

Therefore, the correct option is; Physical evidence

Answer:

Explanation:

A classic projectile motion question. Horizontal motion does not matter whatsoever in the context of this equation as we are looking at the vertical component of velocity only. Since the question states that it is fired horizontally, there is no vertical component of velocity. Thus, v0y = 0.

Assuming the projectile is on the Earth, we can use the free-fall acceleration, 9.8 m/s^2.

The question gives us Δy, which is 37.3m.

Using the second kinematics equation, Δy = v0t + (at^2)/2, we can substitute in the values.

37.3 = 0 + 0.5(9.8)t^2

37.3 = 4.9t^2

7.61224489796 = t^2

t = 2.75902970226 seconds.

Answer:

The first statement appears most accurate.

The last statement also appears accurate, but it does not preclude any contradictory evidence.

The following statements accurately describe a scientific law: There is no contradictory evidence in the current body of knowledge. It is a statement that is true in many, but not all, cases. It is an observation that has been made many times.

The other statements do not accurately describe a scientific law:

"It is an educated guess about how a process occurs" describes a scientific hypothesis or theory, not a law.

"Can be updated or rejected if any contradictory evidence is found" describes the nature of scientific theories, which can be revised or discarded based on new evidence, but laws tend to remain consistent.

Answer:

41.66 km/h

Explanation:

Calculate the distance of 1st travel :

v = d/t

25 km/h = d/1 h

d = 25 km/h × 1 h

Calculate the distance of 2nd travel :

v = d/t

50 km/h = d/2 h

d = 50 km/h × 2 h

Calculate the velocity of trip :

v = d/t

v = (25 + 100)/(1 + 2)

v = 125 km/3 h

So, my velocity for the trip is 41.66 km/h

Answer:

Electric Field intensity is zero.

The reason for that is:

All charges are placed at equal distances from the center of the square and have same magnitude and sign. This means they will exert equal and opposite forces on the test charge at the center. Net force will become Zero.

How are we expected to make an island

Answer:

The acceleration of the car was one meter per second squared.

Explanation:

We can use one of the kinematic equations:

[tex]\displaystyle v_f = v_i + at[/tex]

Where v_f is the final velocity, v_i is the initial velocity, a is the acceleration, and t is the time (in seconds).

The final velocity is 40 m/s, the initial velocity is 35 m/s, and the time is 5 s. Substitute and solve for a:

[tex]\displaystyle \begin{aligned}(40 \text{ m/s}) &= (35 \text{ m/s}) + a(5\text{ s}) \\ \\ 5 \text{ m/s} &= a(5\text{ s}) \\ \\ a &= 1\text{ m/s$^2$} \end{aligned}[/tex]

In conclusion, the acceleration of the car was one meter per second squared.

Answer:

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

Explanation:

Magnetic fields can be mapped out using small plotting compasses : place the plotting compass near the magnet on a piece of paper. move the plotting compass to many different positions in the magnetic field, marking the needle direction each time. join the points to show the field lines.

Answer:

D. the force from the chair on the student

Explanation:

Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.

This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
