defend the use of renewable or non renewable resources. help please will give brainliest
Answer:
Renewable sources are better because they don't damage the environment. As of now, there is a r=lot of damage already done to the environment thanks to non-renewable resources, and soon a lot of this damage will be irreversible. Another good thing about renewable resources is that that it is unlimited, this means that it is a steady source of energy and items.
Non renewable resources are good for the economy. People are so used to using non renewable resources that they might not want to switch over to renewable resources. People will keep buying these product so it is a steady item to invest in and profit off of. Non renewable resources also have a lot more research on them and people have found multiple different ways to utilize it so people might like it more.
which equation correctly represents the gravitational potential energy of a system?
Answer:ME= 1\2mv^2 + mgh
Explanation: I hope this helped.
The correctly represents the gravitational potential energy of a system is = - ΣGM₁M₂/R. Negative sign appears as gravitational force is attractive force.
What is potential energy?Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases.
If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.
Potential energy is a characteristic of systems rather than of particular bodies or particles; for instance, the system made up of Earth and the elevated ball has more potential energy as they become further apart.
Potential energy of a system of particles can be represented as summation of individual's potential energy. Hence, the correctly represents the gravitational potential energy of a system is = - ΣGM₁M₂/R.

A certain space heater that is connected across 220 V and dissipates 1477 W of power in the form of electromagnetic radiation. What is the resistance of the heater?
Hi there!
We can use the power equation:
[tex]P = \frac{V^2}{R}[/tex]
P = Power (W)
V = Potential Difference (V)
R = Resistance (Ω)
Rearrange to solve for Resistance:
[tex]R = \frac{V^2}{P} = \frac{220^2}{1477} = \boxed{32.769 \Omega}[/tex]

A body is moving with a uniform acceleration of 2 m/s2. What does it mean?
Answer:
it means the velocity is changing.
the rate of change of velocity is acceleration
so it means the body is accelerated at 2m/s^2
It means that the body is moving, and getting faster and faster. At any time, it's moving 2 m/s faster than it was moving 1 second earlier.

Suppose you push on a heavy crate, but not hard enough to make it slide. Does a friction force act on the crate?
a.No, the friction force doesn't act.
b.Yes, opposite to your push, just enough so that F = 0.
The net force is 0 because the friction force counteracts or counterbalances the force you apply, which is why the object does not move. Specifically the static friction is holding the object in place and keeping the object static.
Once you apply enough force and overcome that static friction, then the object will move and you'll be dealing with dynamic friction. Dynamic friction is what still holds the object back somewhat and allows the object to slow down and eventually stop (when the force you apply isn't enough anymore).
Without dynamic friction, the object would slide forever until it hit the wall. With something like slippery ice, there is dynamic friction but it's not as large compared to other surfaces.
Complete the sentence using word balanced, normal or tension.
Equal and opposite forces that act on the same object are called____

Joyce and Efua are skating. Joyce pushes Efua, whose mass is 40.0 kg, with a force of 5.00 N. What is Efua’s resulting acceleration?
Answer:
[tex]a=0.125\ m/s^2[/tex]
Explanation:
Given that,
Mass, m = 40 kg
The net force with which Joyce pushes Efua is 5 N.
We need to find Efua’s resulting acceleration. Let it is equal to a. Net force is given by :
F = ma
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{5\ N}{40\ kg}\\\\a=0.125\ m/s^2[/tex]
So, the acceleration is [tex]0.125\ m/s^2[/tex].
The resulting acceleration of Efua is [tex]0.125 \;\rm m/s^{2}[/tex].
Given data:
The mass of Efua is, m = 40.0 kg.
The magnitude of applied force by Joyce is, F = 5.00 N.
The given problem is based on the Newton's Second law of motion. As per the Newton's second law, the applied force is equal to the product of mass and the acceleration of object. Therefore,
F = ma
a = F/m
Solving as,
a = 5.00 / 40
[tex]a = 0.125 \;\rm m/s^{2}[/tex]
Thus, we can conclude that the resulting acceleration of Efua is [tex]0.125 \;\rm m/s^{2}[/tex].

A car is moving down the street at 53km/h. A child suddenly runs into the street. If it takes the driver 0.75 sec to react and apply the brakes, how many meters will the car have moved before it begins to slow down? ANSWER IN METERS
Answer:
11.04m
Explanation:
Convert kilometers to meters: 53km/h x 1000 = 53,000m/h
Convert hours to seconds: 53m/h / 3600 =14.72m/s
14.72 (.75) = 11.04
If this wave has frequency of 15 hz. what is the wavelength of that wave ?
If this wave has a frequency of 15 Hz then the wavelength of the wave would be 2 ×10⁷ m
What is Wavelength?It can be explained in terms of the separation between any two similar successive points on a wave, such as how the wavelength can be determined by calculating the separation between any two successive crests.
According to the following relation, the wavelength and wave frequency are inversely proportional.
C = νλ
Where c is the speed of light and v is the wave's frequency and λ
is the wave's wavelength.
As given in the problem If this wave has a frequency of 15 hz.
As we know C = νλ
by substituting the value of the frequency in the given formula
C = 3×10⁸ m/s
3×10⁸ = 15 ×λ
λ = 3×10⁸/ 15
= 2 ×10⁷ m
Thus, If this wave has a frequency of 15 Hz then the wavelength of the wave would be 2 ×10⁷ m

Starting from rest, a car takes 2.4s to travel 15m. Assuming a constant acceleration, how long will it take the car to travel the next 15m?
Answer:
T = 2.4 + 2.4 = 4.8 [s]
Explanation:
In order to solve this problem, we must use the following kinematics equation and calculate the acceleration value.
[tex]x=x_{o} +v_{o}*t+(\frac{1}{2})*a*t^{2}[/tex]
Vo = inital velocity = 0
x - xo = 15 [m]
t = time = 2.4 [s]
15 = 0.5*a*(2.4)^2
a = 5.208 [m/s^2]
We can use the same equation to find the time.
30 = 15 + 0.5*(5.208)*t^2
t = 2.4 [s]
T = 2.4 + 2.4 = 4.8 [s]
