Explanation:
I can use insulated materials to cover the doors, windows and floors or I use quilted blankets to cover the doors, windows and the floor, this will reduce the sound coming in the room and the sound escaping out of the room.
I can possibly use carpet or floor mats on the floor, especially in front of the door to cover the crack that may be underneath it.
Answer:
your answer for this question is B
Answer:
The ratio of momentum is 1:2 since the velocity is constant and mass is of ratio 1:2
Explanation:
Given
mass of car = 500 kg
mass of truck = 1000 kg
velocity of car = velocity of truck = v = 5 m/s
momentum of car = ?
momentum of truck = ?
We know that the momentum is given by: p = mv , where m is mass and v is velocity.
momentum of car = x v = 500 x 5 = 2500 kg.m/s
momentum of truck = x v = 1000 x 5 = 5000 kg.m/s
The ratio of momentum =
=
= = 1:2
Here we infer that the ratio is 1:2. This is because momentum value depends on mass and velocity of body. In given problem velocity is constant. Hence depends only on mass. The ratio of mass is 1:2 and so the ratio of momentum.
They're called craters.
I actually really like astrology so :)
