Answer: B) exactly the same as the initial momentum.
Explanation:
An inelastic collision occurs when the elements that collide remain together after the collision, and althogh the kinetic energy is not conserved because is transformed into other kinds of energy (thermal energy, for example), the linear momentum does.
This means the initial momentum before the collision will be equal to the final momentum after the collision:

There are a few different formulas for electrical power. They involve
different combinations of voltage, current, and resistance.
==> Power = (current)² x (resistance)
==> Power = (voltage)² / (resistance)
==> Power = (voltage) x (current) .
In this case right now, we know the voltage and current, so maybe
it's a good idea to use the formula that involves voltage and current.
Power = (voltage) x (current)
= (120 volts) x (2.3 Amperes)
= 276 watts .
Answer:
First, the image moves in and out of focus too quickly, so that it is difficult to precisely adjust the focus. Second, you run the risk of crashing the objective into the slide. Use the coarse focus only with the 4x low power objective. You can use the fine focus knob with all objectives.
Explanation:
The distance travelled by the car after the first four hours of the trip is 370 km and the average speed for the first four hours of the trip is 92.5 kmph
v ( t ) = d ( t ) / t
v ( t ) = Velocity with respect to time
d ( t ) = Distance with respect to time
t = Time
For the first four hours, the following details are taken from the graph shown.
d ( 4 ) = 370 km
t = 4 hr
v ( 4 ) = 370 / 4
v ( 4 ) = 92.5 kmph
Average velocity can also be calculated using the formula V = ( u + v ) / 2 if the initial and final velocities are given. u represents initial velocity and v represents the final velocity.
Therefore,
Distance travelled in first 4 hours = 370 km
Average speed in first four hours = 92.5 kmph
