Answer:
Gravitational force, F = 1054.65 N
Explanation:
Given,
The accelerating speed, a = 15 m/s²
The mass of your body, m = 155 lbs
= 70.31 Kg
The gravitational force acting in a body is given by the relation
F = m x g
Where g is the acceleration due to gravity of the in which the velocity of the body changes its speed at a constant rate.
∴ a = g
Substituting the values in the above equation
F = 70.31 x 15
= 1054.65 N
Hence, the gravitational force acting on you, F = 1054.65 N
Answer:
1) Because of the size and time the sound wave moves, an echo is typically transparent and easy to discern. Since reverberations typically don't have enough distance or time to fly, they will pile up on top of each other, making it impossible to understand.
People will detect an echo if the distance between the source of the sound and the reflected body is greater than 50 feet. When a sound wave is bounced off a nearby surface, it may create a reverberation.
2) The speed of sound in hot air is more than that in cold air because air molecules are traveling faster in hot air.
