Answer:
Can a room be gravitationally shielded? No, it can't.
Explanation:
the room cannot be gravitationally shielded because there is only one gravitational charge, in this case is mass. Mass can always be positive. the room can be electrically shielded because there are two type of charge, positive and negative charge than can cancel each other out.
Answer:
The direction of magnetic field produced by a current carrying wire is given by the right hand thumb rule. If the thumb points in the direction of current the fingers curl along the direction of magnetic field.
further, The red end of the compass needle points in the direction of external magnetic field. As the red end of the needle is pointing away from us, the external magnetic field at its location should also be directed away from us. Using the right hand thumb rule, we can see that this is only possible if the current in the wire is flowing upwards.

Answer:
162.5 m is the distance traveled by an object.
Explanation:
Given that,
An object's constant acceleration (a) is .
The time (t) it traveled is 5 seconds.
The object is at rest that is "initial velocity" (u) is 0 m/s.
To find the distance traveled use the below formula,
Where, "s" is distance traveled, "u" is initial velocity, "a" is acceleration and "t" is time taken.
Substitute the given values in the above formula,
s = 162.5 m
Therefore, distance traveled is 162.5 m.
Answer:
Current = 6.82 A
Explanation:
Given the following data;
Power = 1500 Watts.
Voltage = 220 Volts.
To find the current;
Power = current * voltage
Substituting into the equation, we have;
1500 = current * 220
Current = 1500/220
Current = 6.82 Amperes.
Therefore, the current that traverses it is 6.82 Amperes.
Momentum = mass * speed
= 56 * 12
= 672 kg-m/s
