Explanation:
The gravitational force between two objects when they are placed at some distance is given by :
Where
G is universal gravitational constant
m₁ and m₂ are masses
d is the distance between masses
The gravitational force is directly proportional to the product of masses and inversely to the square of the distance between them. It would mean that if the mass of the objects increases, the force will increase while if the distance is increased, the force between objects will decrease.
Answer:
511.545 Newtons
Explanation:
So 1 pound=4.44822 Newton’s so 115 times 4.44822 is 511.5453, then round it to get 511.545 Newtons.
The pressure of the gas is 686 mmhg.
If h = 89 mm
and atmospheric pressure = 775 mmhg
Pressure of the gas = ?
We can find the pressure of the gas by finding the difference between both values.
pressure of the gas = 775 mmhg - 89 mm = 686 mmhg
Answer:
longitudinal
Explanation:
because particles of medium through which the sound is transported vibrate parallel to the direction of the sound wave moves
The chemical energy of petrol is converted to heat energy on combustion. The heat energy is converted to kinetic energy by the use of internal combustion engines in vehicles. The law of conservation of energy is maintained in each process.
<h3>What is kinetic energy?</h3>
The kinetic energy of an object is associated with its motion. It can be related to the mass and velocity as
K.E = 1/2 mv²
Given is a diagram of energy conversion due to combustion.
The chemical energy of petrol is converted to heat energy on combustion. The heat energy is converted to kinetic energy by the use of internal combustion engines in vehicles.
The law of conservation of energy states that the energy can neither be created nor destroyed. It can be only converted to one form to the other.
In the given process, the mass decreases but energy remains the same in all forms of energy.
Hence, the law of conservation of energy is maintained in each process
