Which of the following is an example of an electric force acting at a distance?
A.
Pam rubs a glass rod with wool, then moves the rod over a pile of small paper scraps. The scraps leap into the air and stick to the rod.
B.
Pam applies a force to the head of a nail by pounding it with a heavy, iron hammer. The nail then wedges itself between the fibers of a wooden board.
C.
Pam applies a twisting force to the steering wheel of her car. This force pushes on tubes filled with fluid, which then push the wheels of her car to one side.
D.
Pam jumps out of an airplane. Air rushes past her body at
a very high speed as she falls. She then opens her parachute and feels an upward force.
Answers
Answer:
Option A
Explanation:
An electric force is a charged reaction that causes an attraction or a repulsion between two charged objects. In this case rubbing a glass rod with wool charges up the rod which then turns it into magnetic, which attracts the paper scraps from the ground to the rod where it sticks. The best answer is option A or "Pam rubs a glass rod with wool, then moves the rod over a pile of small paper scraps. The scraps leap into the air and stick to the rod."

If Sam pushes a table with a force of 15 N and it moves a distance of 2 m, how much work did Sam do on the table?
30 J
7.5 J
13 J
17 J
Answers
The computation of the work done is gotten by multiplying the force and distance whish will be A. 30J.
How to calculate work done?It should be noted that the formula for calculating work done is given as:
Work = Force × Distance
where,
Force = 15N
Distance = 2m
Therefore, work done will be:
= Force × Distance
= 15N × 2m
= 30 Joules.
In conclusion, the work done is 30 Joules.

What includes the distance and time at a specific moment?
Answers
Answer:
s = ut + 1/2 att (that's "t" squared), where
s = distance travelled - in metres
u = initial velocity - in meres per second
a = acceleration - in metres per second squared, i.e. metres per second increase in acceleration, per second
t = time taken - in seconds
Explanation:
Time, "t", at a specific moment is a resolved variable, i.e. we know the value, so the equation needs to show distance "s" at that specific time "t". The basic equation is for fixed initial position (when t = 0) , where distance ,"s", = "0", fixed initial velocity, "u", ( at t = 0, s = 0 ) - which can be zero or a value, and fixed (constant) acceleration, "a", ( from t = 0, s = 0, through to t = "specific moment", s = "the answer" ) - which can be zero or a value.

2. Can you rearrange the equation F = kx to get k on one side of the equation
(on its own!). Now, can you rearrange it to get x on its own?
Answers
k = f/x
x = f/k
( / means divide )
The equation connecting force and the displacement k is F= k x. From the spring constant k can be found by dividing F by x and similar to get x by dividing F by k.
What is force?Force is an external agent acting on a body to change it from the state of motion or rest. There are various kinds of force namely magnetic force, frictional force, gravitational force etc.
Force applied on a body if result in displacement of the body it is said to work done on the body. An elastic body like a spring can be stretched or compressed by applying a force on it. Let the change in length or displacement of the elastic body be x.
Then, the force applied on it to make the displacement x is directly proportional to x.
F = k x, where k is the proportionality constant here called the spring constant.
From this the spring constant k = F/x
Similarly, if we know the force f and spring constant k, then x = F/k.

A graph of KE vs the mass of an object is __.
Answers
A graph of KE (kinetic energy) vs the mass of an object is a line, as we know that the kinetic energy depends linearly on the mass of the object.
What is kinetic energy?For an object of mass M moving with velocity v, we define its kinetic energy as:
KE = (M/2)*v^2
We can rewrite it as:
KE = (v^2/2)*M
So, it is a "coefficient" (if we assume that the velocity is constant) times the mass. That gives a linear relationship.
Then we conclude that the kinetic energy depends linearly on the mass, which means that the graph of KE vs the mass of an object is a line.

The limitations include :
depletion of the geothermal sourcehigh costs of investments required for geothermal systemsExplanation:
Geothermal energy originates in form of heat/steam escaping from the inner parts of the earth surface. The steam trapped is converted to electricity through turbines. The hot water pumped by heat pumps can be used to heat homes or for heating purposes in industries.
The limitations of geothermal energy are high initial capital costs for installing the systems, depletion of geothermal sites after sometime, environmental concerns due to greenhouse gases emissions and land requirements for geothermal projects.
