Answer:
I don't now sorry HHHAHAH GOOD LUCK
Answer:
306.8264448 m
47.0016 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Distance traveled by car
Distance traveled by truck
In order to overtake both distances should be equal
The distance the car has to travel is 306.8264448 m
The speed of the car when it overtakes the truck is 47.0016 m/s
Answer;
offgassing
Explanation;
The removal of the embedded gas from a solid object, as happens when formaldehyde in new carpets & furniture is released into the air, is a process known as
offgassing.
It occurs when new, manufactured items in our homes release volatile organic compounds (VOCs) and other chemicals. These compounds include, paints, glue, finishes, among others, they release gases into air.
so for the first one it will be longitudinal wave then the second is transverse wave and the third is electromagnetic wave
Answer:
Both vehicles experience the same change in momentum
Explanation:
Let m represent the mass of the vehicle, and 2m represent the mass of the large truck, and let v represent their initial speed, we have;
The total initial momentum, given as follows;
= 2·m·v - m·v = m·v
The total final momentum, = (2·m + m) ×
By the principle of conservation of linear momentum, the total initial momentum = The total final momentum
m·v = (2·m + m) ×
m·v = 3·m·
∴ v = 3 ×
= v/3
The change in the momentum for the large truck = 2·m·v - 2·m·
Therefore;
The change in the momentum for the large truck = 2·m·v - 2·m·v/3 = 2·m·(v - v/3)
The change in the momentum for the large truck = 2·m·(v - v/3) = 2·m·2·v/3 = 4·m·v/3
The change in the momentum for the car = m·v - m·(-) = m·v - m·(-v)/3 = m·v + m·(v)/3 = 4·m·v/3
Therefore, the change in the momentum for the large truck = The change in the momentum for the car and both vehicles experience the same change in momentum.
