Answer:
Mass on moon = 33.06 kg
Explanation:
Given the following data;
Mass on earth = 200 kg
Weight on earth = 1960 N
Weight on moon = 324 N
To find the mass on moon;
First of all, we would determine the acceleration due to gravity.
Weight = mass * acceleration due to gravity
1960 = 200 * g
g = 1960/200
g = 9.8 m/s²
Next, we find the mass on moon;
Mass on moon = weight on moon/acceleration due to gravity
Mass on moon = 324/9.8
Mass on moon = 33.06 kg
The greater the mass of an object being moved, the greater amount of force needed to move the object,
Answer:
It's often called the law of inertia. Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). ... A more massive object has a greater tendency to resist changes in its state of motion.

A softball player is running at 4.88 m/sec when she slides into second base coming to a stop in .872 seconds. How far did she slide, and what was her acceleration?
Answer:
d=v1t - .5at^2
d=4.88 x .872 - 0.5 x (4.88/0.872) x 0.872^2
d=4.255 - 2.12
d= 2.135m
Explanation:
acceleration is negative because she is slowing down.

Why can water dissolve some ionic compounds, like NH4Cl, as well as some nonionic compounds, like methanol?
Answer:
Water is polar molecule. ... The ionic compounds are dissolved as these ions attract the hydrogen( negative charge attraacts them) and oxygen (positive charge attracts them) whereas methanol is a polar molecule and forms hydrogen bond with water molecules and hence dissolves.

what is the net force of a force of 6N going left towards the object and the 8N going to the right towards the object
The net force when a force of 6N going left towards the object and the 8N going to the right towards the object is found to be 2N toward the right of an object.
What is the net force?Net force may be dfeined as the sum of all of the forces acting on an object. It is categorized as a vector quantity because it has both direction and magnitude to be considered.
Net force in a case where forces of different magnitude and opposite directions will be the difference between greater and lesser force. The combination of the resultant of all the forces acting on an object is called Net Force, which is basically the sum of all the forces acting on that object.
According to the question,
The force going towards the left of an object = 6N.
The force going towards the right of an object = 8N.
The net force = 8 - 6 = 2N towards the right of an object.
Therefore, the net force when a force of 6N going left towards the object and 8N going to the right towards the object is found to be 2N toward the right of an object.

Identify the electromagnets with poles that are reversed from the electromagnet shown above
I've attached a picture of the 3 electromagnets options below the main electromagnet.
Answer:
The third electromagnet is correct.
Explanation:
From the attached image, in the electromagnet above the 3, we can see that the positive terminal comes before the negative terminal at the bottom left.
Now, when it is reversed, they will both move to the bottom right but their position will change with the negative coming before the positive.
Also, the electric current arrow inside the circle points in the north west direction but when it is reversed, it will point in the north east direction.
Also, the winded coil over the pole remains the same.
Thus, the only option that fulfills this reversed positions is the 3rd electromagnet

Therefore, the input force is 9615.38N
Input force calculation.
T0 determine the input force needed 0.78 to raise a house corner from its foundation we need to use the formula for mechanical advantage.
Mechanical advantage = output force/ input force
Given the output force to be 7500N and the mechanical advantage 0.78.
We can rearrange the the formula
IF = 7500/0.78
IF = 9615.38N
Therefore, the input force is 9615.38N

Compare the density of a 1,000,000 kg iceberg to that of a 10 g ice cube taken from the
iceberg. Explain your answer.
ANYONE ASAPP ITS SO IMPORTANT PLSSS
Answer:
The density of the 1,000,000 kg iceberg = The density of the 10 g iceberg
Explanation:
The given quantities of iceberg that will be the basis of the comparison of the densities of the iceberg;
The mass of the iceberg = 1,000,000 kg
The mass of the ice cube taken from the iceberg = 10 g
The density of a substance, is the measure of the mass of the substance per volume of the substance, it is a constant for the substance
[tex]Density = \dfrac{Mass}{Volume}[/tex]
For the iceberg, the density of the iceberg is the property that indicates the volume occupied by a given mass of the iceberg
Because of density, we can estimate that the volume occupied by a 1,000 kg iceberg is 10 times the volume occupied by a 100 kg iceberg
We can write
The density of the 100 kg iceberg = 100 kg/(x m³)
The density of the 1,000 kg iceberg = 1,000 kg/(10 × x m³) = 100 kg/(x m³)
Therefore, the density of the 100 kg iceberg = The density of the 1,000 kg iceberg
Similarly,
The density of the 1,000,000 kg iceberg = The density of the 10 g iceberg because the 10 g iceberg was obtained from the 1,000,000 kg iceberg, and therefore, they have the same density.

A 150 g pinball rolls towards a springloaded launching rod with a velocity of 2.0 m/s to the west. The launching rod strikes the pinball and causes it to move in the opposite direction with a velocity of 10.0 m/s. What impulse was delivered to the pinball by the launcher?
Answer:
I = 1.8 N s, it is directed towards the right
Explanation:
For this exercise we use the relationship between momentum and moment
I = Δp
F t = p_f - p₀
in this case the initial velocity is v₀ = - 2,0 m / s and final velocity v_f = 10,0 m / s, we assume the positive right direction
I = m (v_f - v₀)
let's calculate
I = 0.150 (10.0 - (-2.0))
I = 0.150 (10 + 2)
I = 1.8 N s
as the impulse is positive it is directed towards the right

A boy throws a ball vertically up. It returns to the
ground after 5 seconds. Find
(a) the maximum height reached by the ball.
(b) the velocity with which the ball is thrown up.
Answer:
31.25 m
25m/sec
Explanation:
Given :-
Time = 5sec
V = 0 (in going up)
U = 0 (in comming down)
Find :-
H and U by which it is thrown up
Since the total time is 5 sec ,therefore half time will be taken to go up and another half will be taken to go down .
We know that ,
V = U + gt
0 = U - 10*2.5
U = 25 m/sec
Also,
V² = U² +2gs
0 = 625 - 20s
s = 625/20 = 31.25 m
If the current of a circuit is 1.5 A, and the power is 24 W. what is the resistor?
Answer:
The resistor has a resistance of 10.667 ohms.
Explanation:
By Ohm's Law, voltage ([tex]V[/tex]), in volts, is directly proportional to the current ([tex]i[/tex]), in amperes, and by definition of power ([tex]\dot W[/tex]), in watts, we have the following formula:
[tex]\dot W = i^{2}\cdot R[/tex] (1)
Where [tex]R[/tex] is the resistance, in ohms.
If we know that [tex]\dot W = 24\,W[/tex] and [tex]i = 1.5\,A[/tex], then the resistance of the resistor is:
[tex]R = \frac{\dot W}{i^{2}}[/tex]
[tex]R = 10.667\,\Omega[/tex]
The resistor has a resistance of 10.667 ohms.
Why do you fall forward when you stub your toe on a chair? Explain in terms.
Answer & Explanation:
This can be explained with Newton's first law, Inertia - if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
When you walk, your entire body is in a forwarding motion. If your toe hits an object (in this case, a chair), only this unfortunate toe will stop while the rest of your body continues its forwarding motion, resulting in you falling forward.
find the torque when the work done to more through an angel of 1/4π radians is 3j
Answer:
The torque is approximately 3.82 N·m
Explanation:
The relationship between work done, 'W', and the applied torque, 'τ' can be presented as follows;
W = τ × Δθ
Where;
W = The work done by the torque
τ = The magnitude of the torque
Δθ = The angle through which the object is turned
The parameters for 'W' and 'Δθ' are;
W = 3j
Δθ = 1/4 × π
From W = τ × Δθ, we have;
τ = W/Δθ
∴ τ = 3j/(1/4 × π) ≈ 3.81971863421 N·m
The torque, τ ≈ 3.82 N·m
