Answer:
1. False
2. True
3. True
Explanation:
1- False —> The relation between electric potential and electric field is given such that
Therefore, for a uniform E field, electric potential is linearly proportional to the distance.
2- True —> The electric field lines always cross the equipotential lines perpendicularly.
3- True —> In order to be a potential difference, one source of electric field is enough. The electric potential will decrease radially according to the following formula:
There is no test charge in the formula, only the source charge. Even when there is no test charge, the potential difference between points in space can exist.
Answer:
100 ÷ 9.58 = 10.44 (approximate answer)
The net force is determined is basically who is pushing harder in a specific direction.Like since there bith pushing in the same direction the net force is in the direction that they are pushing.
Answer:
10.09 N
Explanation:
Analogously to Newton's second law, torque can be defined as:
Here, I is the moment of inertia and is the angular acceleration. We have:
Torque is the vector product of the position vector of the point at which the force is applied by the force vector:
Since the effective lever arm is perpendicular to the force, the angle between them is . The magnitud of this vector product is defined as:
.
Solving for F and replacing the known values:
That depends on where you weigh it.
-- On Earth, it weighs 9.807 newtons (2.205 pounds).
-- On the moon, it weighs 1.623 newtons (5.84 ounces).
-- On Jupiter, it weighs 24.79 newtons (5.57 pounds).
BTW ... 1,000 grams of mass is called ' one kilogram '.
