Answer:
The force needs to be applied on the 1 square meter piston to lift the machine is 200 N.
Explanation:
Given that,
Force, 
Area, 
We need to find the force needs to be applied on the 1 square meter piston to lift the machine. We know that the pressure at every point is same due to Pascal's law such that :
So, the force needs to be applied on the 1 square meter piston to lift the machine is 200 N. Hence, this is the required solution.
The answer is 12.36. hoped this helped!
Answer:
If the acceleration of an object remains constant, then its velocity is constant. False
If the acceleration of an object moving along a line is always 0, then its velocity is constant. True
It is impossible for the instantaneous velocity at all times aless than or equalstless than or equalsb to equal the average velocity over the interval aless than or equalstless than or equalsb. True
A moving object can have negative acceleration and increasing speed. False
Explanation:
First of all, before we can talk of acceleration, then there must be a change in velocity. If the velocity of a body is constant, then there will not be any acceleration at all.
If the acceleration is zero, then there is no change in velocity, the velocity is constant.
The instantaneous velocity is always changing all through the motion hence it cannot be determined at all times to equal the average velocity.
If the acceleration is negative, it simply means that the velocity is decreasing with time. Hence there can't be a negative acceleration and increasing velocity.
Answer: 50 km, 0, 27.78 m/s
Explanation:
Given
Circumference of the track is 
Speed of car is 
Car drives for 
(a)Distance traveled is
(b)displacement of the car
It can be observed that 12.5 is a multiple of 50, that is, 50 km can be interpreted as 4 complete rounds of the track.
Therefore, the displacement of the car is zero.
(c)To convert kmph to m/s, multiply the entity by
