Answer:
Explanation:
<u>Given Data:</u>
Momentum = P = 700 kg m/s
Velocity = v = 10 m/s
<u>Required:</u>
Mass = m = ?
<u>Formula:</u>
P = mv
<u>Solution:</u>
m = P / v
m = 700 / 10
m = 70 kg

Three chairs were rolling across a flat office floor. The blue and red chairs are the same mass, and they have more mass than th
e yellow chair. Each chair was hit by another chair, but not from the same direction. Use the information in the diagram to answer.
Which chair(s) experienced the strongest force when hit? How do you know?
a
The blue and red chairs experienced the strongest force because they are both more massive than the yellow chair and they changed speed by the same amount.
b
The red chair experienced the strongest force because it is as massive as the blue chair and has the highest ending speed.
c
All three chairs experienced the same force because they changed speed by the same amount.
d
The blue chair experienced the strongest force because it takes more force to slow an object than it takes to make it go faster.

Answer:
The magnetic force can be found by using the following equation:
Let’s first deal with the magnitude, then we will figure out the direction by using the right hand rule.
The direction of the L is equal to the direction of the current. So, the direction of the L is to the right. The required force is to be pointed upward.
By the right hand rule the magnetic field should be directed towards ‘into the plane’.
Explanation:
In the questions regarding the magnetic field, the cross product and the directions of the vectors are crucial. So, you should use right-hand rule efficiently.
Right-hand rule:
Point your four fingers (except the thumb) towards the same direction as A.
Point your palm towards the same direction as B.
Your thumb should show the direction of C.

Explanation:
Let's call V the voltage provided by the battery in the circuit. M is the multimeter (let's call its internal resistance) and R indicates the resistance of the light bulb.
We know that the meter's internal resistance is 1000 times higher than the bulb's resistance:
(1)
Both the meter and the bulb are connected in parallel to the battery, so they both have same potential difference at their terminals:
Using Ohm's law, , we can rewrite the previous equation as:
where
is the current in the meter
is the current in the bulb
Using (1), this equation becomes
so, the current in the meter is 1000 times less than through the bulb.
