Answer:
The asteroid's acceleration at this point is 
Explanation:
The equation that governs the trajectory of asteroid is given by :
The velocity of asteroid is given by :
At some point during the trip across the screen, the asteroid is at rest. It means, v = 0
So,
Acceleration,
Put t = 0.971 s
So, the asteroid's acceleration at this point is and it is decelerating.
Answer:
Explanation:
Momentum is a concept and is defined as,
Momentum = mass × velocity
So to calculate the momentum of the car
momentum of the car = mass of the car × velocity of the car
So we get,
momentum of the car = 1800 × 30
= 54000 Ns
It would be 12hz because it
It takes significantly stronger magnetic and electric field strengths to move a beam of alpha particles compared with the beam of electrons(betaparticles) because the charge of an alpha particle is twice stronger than a beta particle. Therefore, more energy is needed to move the alpha particle.
