Explanation:
What are the three forms of Newton’s 3rd Law?
Answer:
The third law states that all forces between two objects exist in equal magnitude and opposite direction: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction: FA = −FB.
Answer:
1 an object at motion will remain at motion and a object at rest will remain at rest until a outward force acts upon it
2 force is equal to mass multiple acceleration
3 if an object is acted on with a downward force the object will reflect with a same net force in the opposite direction

Could you pick up a nail using the curved part of the horseshoe magnet farthest from the poles?
Answer & Explanation:
One can pick up a nail using the curved part of the horseshoe magnet farthest from the poles. A horse shoe magnet has magnetic fields all around it. In the presence of magnetic force fields, any magnetic object will be attracted to it.
One can pick up a nail using the curved part of the horseshoe magnet farthest from the poles.
What is magnet?A substance which is negative charged at one end and positive charged at another end creating the magnetic field around it.

What is the density of water?
gram/mL
(fill in the number)
Answer:
1.00 gram per milliliter (1 g/mL). In other words, 1 milliliter of water has a mass of 1 gram. A drop of water is 0.05 mL of water, so its mass would be 0.05 grams.
Explanation:
Why is there less air pressure at higher altitudes?
Air at higher altitudes doesn't have as much air weighing down on it from above.
Air at higher altitudes is cooler and less turbulent.
The molecules in the air lose mass and are less effected by gravity, significantly lowering their weight
The warmer, lighter air rises bringing cooler heaver air to low altitudes.
Answer:
As ailtitudes rises air pressure drops ...... As altitude increases , the amount of gas molecules in the air decreases - so the air becomes less dense than air nearer to the sea level. So there is less air pressure at high altitudes

A. kinetic energy
B. mechanical energy
C. potential energy
D. thermal energy
Answer:
D
Explanation:
You can see the 1st Law thermodynamatic, that energy flow of thermo source.
why isn't it possible to measure the thermal energy of a substance using a thermometer
Answer:
This is because a thermometer is designed to measure the temperature of a substance.
Explanation:
A thermometer is a device which is used to measure the temperature of a body which is known as the measure of the degree of the hotness or coldness of a body.
Temperature is measured in degree Celsius or Kelvin and it is entirely different from thermal energy which is measured in Joules.
The materials of thermometer that are designed to measure temperature only. Therefore, it is not possible to measure thermal energy.
Thermal Energy of a system is defined as the total kinetic energy possessed by the system. And temperature of a system is termed as the measure of average of kinetic energy of particles within the system.
Temperature is generally measured by Thermometers. And it is not possible to measure thermal energy due to following reasons:
Thermal energy is the amount of heat stored in a system. While, temperature is the measure of flow of heat between two points.The calibration of thermometer is done in such a way that it is responsive to the measure of flow of heat, rather than to measure total heat.The material of thermometer cannot withstand the high amount of heat in a system.Thus, thermometers are only used for the purpose of measuring temperatures, rather than thermal energy due to its design specifications.

Explanation:
On the moon, the gravity is 1/6 that of Earth. While on the moon, Buzz Aldrin carried on his back a support system that would weigh over 1760 N on Earth. a) What did the backpack weigh on the moon? b) What was its mass on the moon? please show the work
Answer:
a) 293.[tex]\bar 3[/tex] N
b) Approximately 179.41 kg
Explanation:
The given parameters are;
The gravity (gravitational acceleration) on the moon = 1/6 × The gravity on Earth
The weight of the support system Buzz Aldrin carries = 1760 N
a) Given that the weight of the support system on Earth = Mass of the support system, m × Gravity, g (Acceleration due to gravity) = m·g
The weight of the support system on Earth = m·g
We have;
The gravity on the moon = 1/6 × g
∴ The weight of the support system on the moon = Mass of the support system, m × 1/6 × g = m·g/6
∴ The weight on the of the support system on the moon = m·g/6 = 1/6 × m·g = 1/6 × m·g = 1/6 × The weight of the support system on Earth
The weight on the of the support system on the moon = 1/6 × 1760 N = 880/3 N = 293.[tex]\bar 3[/tex] N
b) The mass, m, of the support system on the moon = The mass, m, of the support system on Earth
The mass, m, of the support system on Earth = Weight of the support system/(Gravity(acceleration due to gravity))
∴ The mass, m, of the support system on Earth = 1760/9.81 ≈ 179.41 kg
∴ The mass, m, of the support system on the moon ≈ 179.41 kg.

A car is traveling in a straight line along a highway at a constant speed of 80 miles per hour for 10 seconds. Find the acceleration.
The acceleration it's the difference of speed (final speed - initial speed) divided by the time. So:
a = Δv/t
In this case the initial speed is equal to 0. The final speed is equal to 80 miles/hour. The time is 10s.
a = 80 miles/hour divided by 10 = 8 miles/hour
Answer:
8
Explanation:
Because as you can see 80/10= 8
Answer is 8

Write an equation of the line in slope-intercept form.
Please explain.
Answer:
y = [tex]-\frac{1}{4}[/tex]x + 3
Explanation:
The equation of a straight line is given as:
y = mx + c
y and x are the coordinates
m is the slope
c is the y -intercept
The y-intercept = 3;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
x₁ = 0
x₂ = 4
y₁ = 3
y₂ = 2
Slope = [tex]\frac{2-3}{4 -0 }[/tex] = [tex]-\frac{1}{4}[/tex]
y = mx + c
y = [tex]-\frac{1}{4}[/tex]x + 3
Why is gravitational acceleration almost always a factor in determining pressure?
Explanation:
Newton's law of universal gravitation states that every object attracts every other object with a force. For any two objects, this force is directly proportional to the mass of each object. The greater the masses, the greater the force of attraction between them. Newton also deduced that this force decreases as the square of the distance between the centers of the objects increases. The farther away the objects are from each other, the less the force of attraction between them.
