What would the gravitational field strength be on a planet with twice Earth's mass
and twice its radius?
78.4 N/kg
39.2 N/kg
19.6 N/kg
9.8 N/kg
4.9 N/kg
Answer:
a = G M / R^2 acceleration due to gravity
aE /aP = (ME / RE^2) / (MP / RP^2) = (ME / MP) * (RP^2 / RE^2)
Since MP = 2 ME and RP = 2 RE
aE / aP = 1/2 * 2^2 = 2
So the gravitational field strength of the planet is 1/2 that of the earth or 4.9 N/kg

Explanation:
I did some research on this today for class, here is what I wrote if you want an understanding why I think A is the answer: Exercise can cause a temporary boost in the production of macrophages, the cells that attack bacteria. During moderate exercise, immune cells circulate through the body more quickly and are better able to kill bacteria, which can help you not get colds and viruses, after a few hours the immune system will return to normal, the more you exercise the longer the effects will last. So the more you exercise the better your immune system will be!

1. A buoyant force of 790 N lifts a 214 kg sinking boat.What is the boat's
net acceleration?
Answer:
The net acceleration of the boat is approximately 6.12 m/s² downwards
Explanation:
The buoyant or lifting force applied to the boat = 790 N
The mass of the boat lifted by the buoyant force = 214 kg
The force applied to a body is defined as the product of the mass and the acceleration of the body. Therefore, the buoyant force, F, acting on the boat can be presented as follows;
Fₐ = F - W
The weight of the boat = 214 × 9.81 = 2099.34 N
Therefore;
Fₐ = 790 - 2099.34 = -1309.34 N
Fₐ = Mass of the boat × The acceleration of the boat
Given that the buoyant force, Fₐ, is the net force acting on the boat, we have;
F = Mass of the boat × The net acceleration of the boat
F = -1309.34 N = 214 kg × The net acceleration of the boat
∴ The net acceleration of the boat = -1309.34 N/(214 kg) ≈ -6.12 m/s²
The net acceleration of the boat ≈ 6.12 m/s² downwards
The boat's net acceleration is -6.12 m/s²
Given that:
Buoyant force = 790 N, mass (m) = 214 kg, acceleration due to gravity (g) = 9.81 m/s²
Net force = Buoyant force - mg = 790 - (214 * 9.81) = -1309.34 N
Net acceleration = Net force / mass
Net acceleration = -1309.34 N / 214 kg = -6.12 m/s²
The boat's net acceleration is -6.12 m/s²

B) 30 mph northwest
Explanation: Vector quantities have both direction and magnitude. In this case the direction is northwest, and magnitude is 30 mph.
The following is a vector quantity, 30 mph northwest. Option B is correct.
What is a vector quantity?A vector quantity is a physical quantity that has both magnitude and direction. Examples of vector quantities include displacement, velocity, acceleration, force, and momentum.
In contrast, a scalar quantity is a physical quantity that has only magnitude and no direction associated with it. Examples of scalar quantities include speed, distance, mass, temperature, and time.
Here,
A vector quantity is a physical quantity that has both magnitude and direction. In this case, the magnitude is 30 mph and the direction is northwest, which makes it a vector quantity.
Option A is a scalar quantity because it only has a magnitude, but no direction associated with it. Option C is also a vector quantity because it has both magnitude and direction, but it is not given a direction in the question. Option D is a scalar quantity because it only has a magnitude.
Thus, the following is a vector quantity, 30 mph northwest. Option B is correct.

how do forces work in nature?
The strong force is that force which cause the basic pieces of an atom to hold together. The weak force is radiation; this force is instrumental in things decaying. Electro-magnetism is the charged field which surrounds iron based materials or objects.
Force make objects movable and to change their state. Various kinds of forces in nature balances altogether every processes in nature. The energy we gain or lost is due to some kind of force and resultant displacement.
What is force?Force is an external agent acting on an object to change its state of motion or to deform it. Force is a vector quantity and is characterized by its magnitude and direction. There are various kinds of forces such as gravitational force, magnetic fore, frictional forces, nuclear force etc.
Its due to gravitational force by earth that we are standing on the ground. We experience a weight due to this effect. Similarly the rotating current in the earth core generates the magnetic force of earth.
Every objects need a force to change its state or rest or motion. Similarly, the work done in any fields is the result of any force applied on the system.

Explanation:
Newton's second law of motion states that larger things need more force to move them than lighter
things. What would be an example of this law in action?
Answer:
weight of two people
Explanation:
Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.
2nd Law: F=ma
a= change in velocity/time
a=F/m
say both objects must accelerate at a=2 m/s^2
object A is a wood plank, which is roughly 10 kg
object B is my metal ball, which has a mass of 100kg
now, solving for F applied to both objects
Fwood=(10kg)(2 m/s2)= 20 N
Fmetal=(100kg)(2 m/s2)= 200 N
the F needed to move the metal ball is 10 times greater than the F needed to move the wood plank. Hope this helped, I'm about to go fail my physics exam :)

If a race car wants to change its velocity then a net force is
required to cause the necessary
Answer:acceleration
Explanation:
We define acceleration as the rate of change of velocity. So if a moving object wants to change its velocity, it needs to accelerate.
Thus the statement would be:
"If a race car wants to change its velocity then a net force is required to cause the necessary acceleration".
--------------------------------
Acceleration defines how the velocity changes, suppose that you are in one dimension and you move with positive velocity, if you have also positive acceleration your velocity will increase.
If you have negative acceleration your velocity will decrease.
But if we go to 2 dimensions we can see that acceleration is way more complex, because it is what allows the changes of direction of motion (by changing the direction of the velocity).
Now, acceleration comes from Newton's second law of motion:
F = m*a
Force equals mass times acceleration.
Then if we know that a car wants to change its velocity, it needs to apply a force such that it causes the necessary acceleration to change the velocity as wanted.
From this we can see that the complete statement would be:
"If a race car wants to change its velocity then a net force is required to cause the necessary acceleration"

What is the current of a 24 ohm heating coil in a coffee maker plugged into a 120V outlet?
What voltage will produce 6 amps through a circuit that has 10 ohms of resistance?
Answer:
Current, I = 5A.
Voltage, V = 60V.
Explanation:
In part 1;
We were given the following data:
Resistance = 24 ohm
Voltage = 120V
To find the current,
According to ohm's law which states that, the current flowing through a conductor is directly proportional to the amount of potential voltage across its terminal and inversely proportional to the opposition to the flow of current (resistance) of the conductor.
Mathematically,
[tex] V = IR[/tex]
Where, V represents voltage measured in volts (v).
I represent current measured in amperes (A).
R represent resistance measured in ohms.
[tex]I = \frac{V}{R}[/tex]
Substituting into the equation, we have;
[tex]I = \frac{120}{24}[/tex]
I = 5amp
For part 2.
Given the following data
Current = 6
Resistance = 10ohms
Velocity =?
[tex] V = IR[/tex]
[tex] V = 6 * 10[/tex]
V = 60V
