Answer:
The net outward force is exerted on a square window of the house is .
Explanation:
Given that,
Pressure = 1.02 atm
External air pressure = 0.910 atm
Distance = 2.03 m
We need to calculate the net outward force
Using formula of force
Where, P = pressure
F = force
A = area
Put the value into the formula
Hence, The net outward force is exerted on a square window of the house is .
Answer:
L = 499 m
Explanation:
Answer:
No, the ball will not clear the fence.
Solution:
Angular velocity,
Height, h = 1.2 m
Angle,
Distance covered by the ball, d = 110 m
Length of the fence, l = 1.2 m
Radius of the axis, R = 46 cm = 0.46 m
Now,
To calculate the linear velocity of the ball, v:
Total time taken:
The distance at which the ball falls, with a = 0 is given by:
Since, the ball has to clear a fence 1.2 m long and a t a distance 110 m away, clearly it will not be able to cross it.
