The correct option is this: THIS IS THE DEMONSTRATION OF BOYLE'S LAW. AS THE VOLUME INCREASES, THE PRESSURE DECREASES AND THE MARSHMALLOW WILL GROW LARGER.
Boyle's law states that the volume of a gas is inversely proportional to the pressure of the gas at constant temperature. The law explains the relationship between the volume and pressure of a gas at constant temperature.
Answer:
Potential energy = 3635.8 Joules
Explanation:
Given that,
Weight lifted by a weight lifter is 12 kg
It lifts to a height of 1.75 m
We need to find the potential energy to the wights now have. The energy possessed by an object due to its position or height above ground is called potential energy. Its formula is given by :
P = mgh
g is the acceleration due to gravity
So, the potential energy is 3635.8 joules.
FALSE, a hypothesis REQUIRES an observed pattern in nautre, WITH attempting to explain.
Answer:
d)30,000 N
Explanation:
Solution:
mass(m)=1000kg
initial velocity (u)=0m/s
final velocity (v)=15m/s
So,
acceleration (a)=(v-u)/t
=(15-0)/10
=1.5m/s^2
Atlast,
Force(F)=m×a
=20000×1.5
=30,000 N
