Answer:
Explanation:
Hello.
In this case, for this uniformly accelerated motion in which the car starts from rest at 0 m/s and travels 18 m in 3.0 s, we can compute the acceleration by using the following equation:
Whereas the final distance is 18 m, the initial distance is 0 m, the initial velocity is 0 m/s and the time is 3.0 s, that is why the acceleration turns out:
Best regards.
Answer:
W = 600 J
Explanation:
We have,
According to attached figure,
Height of the inclined plane is 60 m
Force acting on the block is 10 N
It is required to find the work must be done against gravity to move it to the top of the incline. The work done is given by :
W = mgh
or
So, the work done against the gravity is 600 J.
Answer:
The minimum gauge pressure is 0.4969 atm.
Explanation:
Given that,
Density = 1040 kg/m³
Height = 4.94 cm
We need to calculate the pressure
Using formula of pressure
Where, =density
h = height
Put the value into the formula
Pressure in atmospheres
Hence, The minimum gauge pressure is 0.4969 atm.
