How many hours would it take a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.
It would take 3 hours and 45 minutes, for a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.
Calculation
Round off 3.75 to the nearest one to give the hour value i.e., 3.The minutes are obtained by multiplying the fractional portion of the decimal value by 60, or 0.75 x 60 = 45.we have 3 hours and 45 minutes.What is speed?The distance traveled in a unit of time is called speed. It refers to a thing's rate of movement.This scalar quantity known as speed is the velocity vector's magnitude, It has no clear direction.A faster rate of movement is indicated by a higher speed. It is travelling more slowly if the speed is lower. It has zero speed if it isn't moving at all.The formula: can be used to determine the constant velocity of an object traveling straight forward.r = d / twhere,
r stands for rate or speed (sometimes denoted as v, for velocity)
d is the traveled distance.
t is the amount of time needed to finish the movement.
The average speed of an object over a period of time is given by this equation. We can see the object's average speed here, however at some moments over the time frame, it may have been moving faster or slower.As the time interval gets closer to zero, the maximum average speed is reached. The speed at that moment is what you see when you look at a speedometer in an automobile. While you may have briefly reached a speed of 60 mph, your average speed over the course of 10 minutes could have been much higher or much lower.M/s is the SI unit of speed (meters per second). Miles per hour or kilometers per hour are the most widely used units of speed in everyday life. A typical speed at sea is in knots, or nautical miles per hour.To learn more about speed, refer to https://brainly.com/question/24739297

How much energy must be absorbed by water with a mass of 0.5 kg in order to raise the temperature from 30°c to 65°C?
Water has a specific heat of 4,190 j/kg°C
Answer:
Q = 67.04 [J]
Explanation:
In order to solve this problem, we must use the following equation of thermal energy, which relates mass to specific heat and temperature change.
[tex]Q = m*c_{p}*(T_{2} -T_{1})[/tex]
where:
Q = thermal energy [J]
m = mass = 0.5 [kg]
Cp = specific heat = 4,190 [J/kg°C]
T2 = final temperature = 65 [C]
T1 = initial temperature = 30 [C]
Now replacing:
Q = 0.5*4.190*(65 - 30)
Q = 67.04 [J]

B. When researchers draw conclusions that are consistent with their observations.
C. When researchers blind themselves to participants in the groups, so they don't accidentally reveal the information.
D. When the personal opinions, Ideas, or judgments of the researchers influence their research.
When the personal opinions, Ideas, or judgments of the researchers influence their research, then the experimental investigation and observation are considered biased, therefore the correct answer is option D.
What is the scientific claim?Scientific claims are statements made in science based on an experiment.
These Scientific claims are backed by experimental data and their true results obtained from scientific investigation and experimentation.
The right response is option D because experimental study and observation are deemed biased when the researchers' own ideas, beliefs, or judgments affect their findings.

An object is thrown downward from the top of a 175 meter building with an initial speed of 10m/s
Answer:
Explanation:
we can look for the final velocity of the object using the eqaution of motion as shown:
v² = u²+2gH
v is the final velocity
u is the initial velocity = 10m/s
g is the acceleration due to gravity = 9.81m/s²
H is the height of the object = 175m
Subxtitute the given parameters inti the formula and get v:
v² = 10²+2(9.81)(175)
v² = 100+3433.5
v² = 3533.5
v = √3533.5
v = 59.44m/s
Hence the final velocity of the object is 59.44m/s

Which is a vector quantity?
A distance
B. time
C.mass
D.velocity
Can anyone help,please?
Answer:
D. Velocity
Explanation:
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

A shopping cart given an initial velocity of 2.0 m/s undergoes a constant acceleration to a velocity of 13 m/s. What is the magnitude of the carts acceleration if the time is 4.0?
Also if your really smart and have instagram please dm imaswagmeal and help me pls
Answer:
The acceleration is a = 2.75 [m/s^2]
Explanation:
In order to solve this problem we must use kinematics equations.
[tex]v_{f} = v_{i} + a*t\\[/tex]
where:
Vf = final velocity = 13 [m/s]
Vi = initial velocity = 2 [m/s]
a = acceleration [m/s^2]
t = time = 4 [s]
Now replacing:
13 = 2 + (4*a)
(13 - 2) = 4*a
a = 2.75 [m/s^2]

What are series and parallel circuit?Electrical networks and two-terminal components can be linked either serially or parallelly. The electrical network that results will have two terminals and be capable of operating in either a series or parallel topology.
It depends on your point of view whether a two-terminal "thing" is an electrical network (like resistors connected in series) or an electrical component (like a resistor). In this article, a two-terminal "thing" that participates in series/parallel networks will be referred to as a "component."
Each component connected in series travels the same "electrical path" and carries the same amount of current—equal to the network's current—through it.

Lisa has a mass of 52 kilograms. How much does Lisa weigh in Newtons? How much does she weigh in pounds? (Use g = 9.8 m/s)
Answer: 510 in Newton’s and 115 lbs
Explanation:
Considering the definition of weigh, Lisa weighs 0.5096 N or 0.1146 pounds.
Mass is the amount of matter that a body contains, while weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.
The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.
Weight can be calculated as the product of mass and acceleration due to gravity:
W=m×g
In this case, you know:
m= 52 g= 0.052 kg (being 1000 g=1 kg)g=9.8 m/s²Replacing in the definition of weigh:
W=0.052 kg×9.8 m/s²
Solving:
W= 0.5096 N
1 newton equals 0.2248 pound. Then W=0.5096 N= 0.1146 Pounds
Finally, Lisa weighs 0.5096 N or 0.1146 pounds.

If a person pulls a cart to the right at 5N of force and another person pulls to the left with a 15N of force? What is the net force and it what direction
Answer:
The net force is 10 [N] acting to the left
Explanation:
To solve this type of problem we must make a sum of the forces acting on the cart, since the forces are vectors, we know that vectors can be added, In this way forces that go in the same direction are added and forces in opposite directions are subtracted.
FL = force to the left = - 15 [N]
FR = force to the right = 5 [N]
FT = Resultant force [N]
- 15 + 5 = FT
FT = - 10 [N]
The negative sign tells us that the force acts to the left.
