Matter cannot be created or destroyed under normal conditions. The big rock is weathered by the river water and goes through wear and tear because of its motion, and finally turns into gravel. So the lost part of the rock has been converted to soil .-.
From Newton's second law, F= ma
F = 2000 kg x 15 m/s^2 = 30000 N
Answer:
3.62 x 10^15 N
Explanation: We will solve this problem by using Newton's Law of Universal Gravitation.
F = <u>G m1*m2/</u> r^2 where
F= Force of attaction between each object
m1 and m2 the masses of the objects
r squared the distance between the objects
G= Gravitational constant
Working in the S.I the answar becomes:
F= 6.67x10^-11 * 3.1x10^20*7.4x10^18/(6.65x10^6)^2
F= 3.62 x 10^15 N
Answer:
The gauge pressure is equal to 147 kPa.
Explanation:
The pressure exerted by fluid is given by :
Where
is density of water
h is height
So, put all the values,
or
P = 147 kPa
So, the gauge pressure is equal to 147 kPa.
