Answer:
other part will move with momentum 0.5 kg m/s towards west
Explanation:
As we know that the during the explosion event the time interval is very small and there is no impulsive force on the firecracker during this time
so here we can say that the momentum will remains conserved during the this event
now if the initial momentum of the firecracker is zero
then the final momentum must be zero
so here we can say
towards east
now from above equation
so the other part will move with momentum 0.5 kg m/s towards west
The correct answer for the question that is being presented above is this one:
Phi = BAsin(theta)
<span>1. Phi(i) = BA </span>
<span>2. Phi(f) = 0 </span>
3. EMF = N(phi(i)-phi(f))/deltat
Here are the follow-up questions:
<span>1. What is the total magnitude Phi_initial of the magnetic flux through the coil before it is rotated? </span>
<span>2. What is the magnitude Phi_final of the total magnetic flux through the coil after it is rotated? </span>
<span>3. What is the magnitude of the average emf induced in the coil?</span>
Answer:
125.5J
Explanation:
Given parameters:
Mass of the bowling ball = 6.1kg
Height of lifting = 2.1m
Unknown:
Increase in the ball energy = ?
Solution:
The ball has changed position by moving it from one point to another. So, it has acquired more potential energy.
Potential energy = mgh
m is the mass
g is the gravity
h is the height
Now insert the given parameters and solve;
Potential energy = 6.1 x 9.8 x 2.1 = 125.5J
I’m slightly confused about the wording of the question but if both the same y-intercept that means both company’s have the same flat rate charge for artwork.
