Answer:
I remember learning about this in health class. I believe the answer is quality of life.
Explanation:
Let us say that Cp is the specific heat of the metal object.
Then we do a heat balance (heat lost by metal = heat gained by water):
- 19g * Cp * (22degC – 96degC) = 75g * 4.184J/g degC * (22degC
– 18degC)
<span>Cp = 0.893 J/g degC</span>
En caso de una colisión de bajo nivel de gravedad podría golpearse con el tablero del carro o en la parte del sillón (si esta sentado en la parte trasera). Pero si es muy grave la colisión podría salirse del carro por el cristal.
Answer:
The the recoil velocity of the hunter is 0.056 m/s in opposite direction of the bullet.
Explanation:
Given;
mass of bullet, m₁ = 4.2 g = 0.0042 kg
mass of hunter + gun = 72.5 kg
velocity of the bullet, u = 965 m/s
Momentum of the bullet when it was fired;
P = mv
P = 0.0042 x 965
P = 4.053 kg.m/s
Determine the recoil velocity of the hunter.
Total momentum = sum of the individual momenta
Total momentum = momentum of the bullet + momentum of the hunter
Apply the principle of conservation of momentum, sum of the momentum is equal to zero.
Therefore, the the recoil velocity of the hunter is 0.056 m/s in opposite direction of the bullet.
Answer:
In 3 hours, the cars will be 297 miles apart.
Explanation:
Speed=Distance/Time
Distance= Speed X Time
Speed of 1st Car=44 miles/hr
Distance=44 X Time taken = 44t
Speed of 2nd Car=55 miles/hr
Distance=55 X Time taken = 55t
Total Distance Covered by both Cars = 44t + 55t = 99t
The cars are 297 miles apart, therefore:
99t = 297
t = 3 hours
It means that in 3 hours, the distance between the cars is 297 miles.
