The Hubble Space Telescope has a mass of 1.16*10^ 4 kg and orbits the Earth at an altitude of 5.68 * 10 ^ 5 above Earth's surface. Relative to infinitydetermine the potential energy the telescope at this location. Would the formula be Ep=-Gm1m2/r or positive G since it’s relative to infinity
Answer:
[tex]E=8.13\times 10^{12}\ J[/tex]
Explanation:
Given that,
The mass of a Hubble Space Telescope, [tex]m_1=1.16\times 10^4\ kg[/tex]
It orbits the Earth at an altitude of [tex]5.68\times 10^5\ m[/tex]
We need to find the potential energy the telescope at this location. The formula for potential energy is given by :
[tex]E=\dfrac{Gm_1m_e}{r}[/tex]
Where
[tex]m_e[/tex] is the mass of Earth
Put all the values,
[tex]E=\dfrac{6.67\times 10^{-11}\times 1.16\times 10^4\times 5.97\times 10^{24}}{5.68\times 10^5}\\\\E=8.13\times 10^{12}\ J[/tex]
So, the potential energy of the telescope is [tex]8.13\times 10^{12}\ J[/tex].

When you are describing the rate that a race car goes around a track, should you use the term speed or velocity to describe the motion
Answer:
Speed
Explanation:
Speed is a description of how fast an object moves; velocity is how fast and in what direction it moves. In physics, velocity is the speed in a given direction.
Answer:
speed
Explanation:
Speed is a description of how fast an object moves; velocity is how fast and in what direction it moves. In physics, velocity is speed in a given direction. When we say a car travels at 60 km/h, we are specifying its speed. When we say a car moves at 60 km/h to the north, we are specifying its velocity.
Mr Mann cut a cucumber. Mr Mann said, you have performed a chemical change. Is he right?
Answer:
No.
Explanation:
The cut cucumber is still a cucumber.
Answer:
Nope.
Explanation:
Chemical change is transforming the cucumber into a pickle. However, you need vinegar, so it isn't a full change.
Therefore, Mr. Mann would not be right either way, because all he did was cut a cucumber, and he should probably get some help with all this "chemical change".
9. How is spring potential energy determined from a force versus position graph?
Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.
Explanation:
:)
By getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.
What will be the potential energy?As we know that potential energy is defined as the energy possessed by the body due to its position with respect to other positions.
For an example the potential energy of an object if it is placed at height h will be due to the gravitational acceleration of the earth and is given by [tex]PE=mgh[/tex]
Similarly, for a spring-mass system, the potential energy will be due to the weight of the mass that will be the force exerted by the mass on the spring so there will be an extension in the spring.
So this extension will be found out by the force and displacement graph as the position of the mass attached to the spring goes down so the potential energy can be calculated as the
[tex]PE= F\times X[/tex]
[tex]F=mg[/tex] weight of the mass
X= deflection of the spring
Thus by getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

the shock absorbers in a car act as a big spring with k= 21900 N/m. when a 92.5 kg person gets in, how far does the spring stretch?
Answer: 0.04139m
Explanation:
First, we need to calculate the weight of the man which will be:
Weight = mass × acceleration due to gravity
Weight = mg
Weight = 92.5 × 9.8
Weight = 906.5N
Then, we calculate the force which will be:
F = kx
mg = kx
x = mg/k
x = 906.5/21900
x = 0.04139m.
The spring stretched for 0.04139m.

What would be the effect of an increase in greenhouse gas concentration in the atmosphere on Earth's average temperatures?
Answer:
See Explanation
Explanation:
Greenhouse gases are those gases that are believed to trap infrared rays close to the earth surface. Infrared radiation is otherwise known as heat rays due its heating effect.
Increase in the concentration of these greenhouse gases will ultimately lead to a gradual increase in the earth's average temperature. This phenomenon is referred to as global warming.

A 75.6-kg circus performer is fired from a cannon that is elevated at an angle of 37.2° above the horizontal. The cannon uses strong elastic bands to propel the performer, much in the same way that a slingshot fires a stone. Setting up for this stunt involves stretching the bands by 2.70 m from their unstrained length. At the point where the performer flies free of the bands, his height above the floor is the same as the height of the net into which he is shot. He takes 2.34 s to travel the horizontal distance of 26.9 m between this point and the net. Ignore friction and air resistance and determine the effective spring constant of the firing mechanism.
Answer:
The effective spring constant of the firing mechanism is approximately 21.804 N/m
Explanation:
The mass of the circus performer, m = 75.6 kg
The angle of elevation above the horizontal, θ = 37.2°
The instrument the cannon uses to propel the performer = Strong elastic band
The length by which the band stretches, x = 2.70 m
The height of the performer above the floor at the point the performer flies free of the bands = The height of the net into which he is shot
The time he takes to travel the horizontal distance between the point he is shot and the net, t = 2.34 s
The horizontal distance between the the point he is shot and the net, dₓ = 26.9 m
Therefore, the horizontal component of the velocity, vₓ, can be found with the following kinematic equation of motion;
vₓ = dₓ/t
∴ vₓ = 2.70 m/(2.34 s) = (15/13) m/s
By the resolution of the initial velocity, 'v', into the horizontal and vertical component, we have;
The horizontal component, vₓ = v × cos(θ)
∴ v = vₓ/(cos(θ))
v = (15/13)/(cos(37.2°)) ≈ 1.45
The initial velocity, v ≈ 1.45 m/s
The kinetic energy given to the circus performer by the elastic band, K.E., is given as follows;
K.E. = (1/2)·m·v²
Where;
m = The mass of the performer = 75.6 kg
v = The velocity given to the performer ≈ 1.45 m/s
∴ K.E. ≈ (1/2) × 75.6 × 1.45² ≈ 79.475
∴ K.E. ≈ 79.475 J
The kinetic energy, K.E., given to the performer, (1/2)×m×v² = The kinetic energy of the elastic band = (1/2)×k×x²
Where;
k = The effective spring constant of the firing mechanism
x = The extension of the sling = 2.70 m
Therefore, we get;
K.E. = (1/2)·m·v² = (1/2)·k·x²
∴ K.E. ≈ 79.475 J = (1/2) × 75.6 × 1.45² = (1/2) × k × (2.70 m)²
∴ 79.475 J ≈ (1/2) × k × (2.70 m)²
k = 79.475 J/((1/2) × (2.70 m)²) ≈ 21.804 N/m
The effective spring constant of the firing mechanism, k ≈ 21.804 N/m.

A 4.03 x 10-5 F capacitor stores 5.15 x 10-3 J of energy. What is the voltage across the capacitor?
Answer:
V = 0.06255 Volts
Explanation:
Given the following data;
Capacitance = 4.03 * 10^{-5} F
Energy = 5.15 * 10^{-3} J
To find the voltage across the capacitor;
Mathematically, the energy stored in a capacitor is given by the formula;
E = ½cv²
Where;
C is the capacitor
E is the energy stored
v is the voltage.
Substituting into the formula, we have;
5.15 * 10^{-3} = ½ * 4.03 * 10^{-5} * v²
0.00515 = 0.00002015 * v²
V² = 0.00002015/0.00515
V² = 0.003912
Taking the square root of both sides, we have;
V = √0.003912
V = 0.06255 Volts

16 V
