Answer:
The velocity of the truck after the collision is 20.93 m/s
Explanation:
It is given that,
Mass of car, m₁ = 1200 kg
Initial velocity of the car, 
Mass of truck, m₂ = 9000 kg
Initial velocity of the truck, 
After the collision, velocity of the car, 
Let 
is the velocity of the truck immediately after the collision. The momentum of the system remains conversed.
So, the velocity of the truck after the collision is 20.93 m/s. Hence, this is the required solution.
Answer:
false
A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. ... The cause is called the independent variable; and the effect is called the dependent variable.
Answer:
Explanation:
Power = current * voltage
Power = 3.6 * 1.75
Power = 6.3 watts.
I hope this diode does not have to do this for very long. The power dissipation is above the diode's rated power -- a condition that won't last forever.
The power dissipation is 6.3 watts.
Answer: 146.1 kg/m/s
Explanation: Momentum is equal to mass times velocity, so you do 9.74 kg times 15 m/s and get 146.1 kg/m/s.
Answer:
180000 N
Explanation:
According to Newton's law of gravitation
F= G m1 m2 / r^2
This expression shows that if distance is reduced to half the gravitational force will increase 4 times.
