Answer:
C) either of these depending on speed
Explanation:
In classical mechanics, the momentum of a body is defined as the product of its mass and its velocity at a given time. Although the bullet has a smaller mass than the container ship, its momentum may be greater or lesser than container ship's, depending on its speed.
Answer:
Pressure = 24000 N/m²
Explanation:
Given the following data;
Force = 120N
Area = 0.5cm² to meters = 0.5/100 = 0.005 m²
To find the pressure;
Pressure= force/area
Pressure= 120/0.005
Pressure = 24000 N/m²
Therefore, the pressure on the archer's fingers is 24000 Newton per meters square.
Answer:
false
Explanation:
it's hydrogen. also hydrogen has one proton and stuff and helium two
Answer:
The average velocity for the time period beginning when t=1 and lasting 0.1 seconds = 16.40 ft/s.
Explanation:
Given that the height of the ball at time t is
The average velocity of an object is defined as the total displacement covered by the particle divided by the total time taken in covering that displacement.
If are the heights of the ball at time and , then the total displacement covered by the ball from time to is .
Thus, the average velocity of the ball for the time interval is given by
For the time interval, beginning when t = 1 second and lasting 0.1 seconds,
True only some changes in speed or direction are caused by forces
