5. There is a bell at the top of a tower that is 45 m high. The bell's mass is 200 kg. The bell has energy. Calculate it.
45000
900000 J
9000 J
88200 J
Answer:
Explanation:
Since the bell is at rest in an elevated position, we can assume that it only has potential energy.
U=mgh is the formula for potential energy where U=potential energy, m= mass, g=acceleration due to gravity, and h=height.
Plug in known variables....
U=200kg*9.8m/s^2*45m
U=88200 joules of potential energy or letter D.

Which arrow represents the direction of upthrust?
look at the photo
The arrow A represents the direction of upthrust.
What is thrust?Thrust is the pressure acting generally on a surface. Its SI unit is Newton (N). Thrust is the pressure that actions a plane via the air. Thrust is used to triumph over the drag of an airplane, and to conquer the load of a rocket.
As anxiety is the significance of pressure, it is measured in newtons (or now and again kilos-force) and is usually measured parallel to the string on which it applies. Thrust is a response pressure defined quantitatively by means of Newton's.

A kid is bouncing on a pogo stick. He oscillates 22.0 times in 14.9 S. What is his frequency? (Unit = Hz)
Answer:
1.4765 Hz
Explanation:
right on acellus
The frequency of an event is the inverse of time period.The frequency of the kid on bouncing the pogo stick is 1.47 Hz.
What is frequency?Frequency of an event is is the number of occurance of that event in unit time. It is the inverse of time period of that event. Hence frequency has the unit of s⁻¹ which is equivalent to Hz.
The frequency of a wave is the number of wave cycles per unit time. Frequency is directly related to the energy of the vibration or wave. Hence, as the frequency increases, energy increases.
Given that, the number of oscillations from the bouncing of the pogo stick is 22 times in 14.9 seconds. Thus , number of oscillations in 1 second is:
22 /14.9 s = 1.47 Hz.
Therefore, the frequency of the event created by the kid is 1.47 Hz.

define amoeba what are your plans
Answer:
Amoeba (plural = amoebae) is a well known genus of unicellular organism, a protist. One of its most common species, the Amoeba Proteus, is about 0.2 to 0.3 mm large. The amoeba was first discovered by August Von Rosenhof in 1757.[1] It is a genus of protozoa that moves with false feet, called pseudopodia.

Which of the following will best transport electrons around an electrical circuit
Answer:
b is correct!!!!!!!!!!!
The best transport electrons around an electrical circuit are connected in series. Thus, the correct answer would be option (B) are connected in series.
What is alternating current (AC)?An alternating current (AC) circuits continuously switches the direction of electron flow back and forth, which can result in fluctuations in voltage and current.
On the other hand, in a direct current (DC) electrical circuit, the electrons flow in one direction, from the negative terminal of the power source to the positive terminal. This unidirectional flow of electrons provides a consistent and stable flow of electricity throughout the circuit.
Connecting components in series mean that they are connected end-to-end, and the current flowing through them is the same.
Overall, the best option to transport electrons around an electrical circuit are to connect in series.
Therefore, the correct answer would be option (B) are connected in series.

Explanation:
The question is with regards to the relationship between work, energy, power, and velocity
The mass of each of the persons running up the staircase = Different
The time it takes each person to run up the stairs = Equal time
Let, 'm₁' and 'm₂' represent the mass of each of the persons that ran up the stairs and m₁ > m₂
Let 't' represent the equal time it takes then to run up the stairs
Let 'h' represent the height of the stairs
The energy, 'E', it takes to run up the stairs is equal to the potential energy, P.E., obtained at the top of the stairs
P.E. = m·g·h
Where;
m = The mass of the person at an elevated height
g = The acceleration due to gravity = Constant
h = The height reached above ground level
Given that the height reached is the same for both of the persons, we have
For m₁, P.E.₁ = m₁·g·h and for m₂, P.E.₂ = m₂·g·h
Therefore, where, m₁ > m₂, we have;
P.E.₁ > P.E.₂
∴ E₁ > E₂
Power, 'P', is the rate at which energy is expended
∴ Power, P = E/t
∴ P₁ = E₁/t > P₂ = E₂/t
Therefore, the person with the greater mass, 'm₁', uses more power than the person of mass 'm₂', in running up the stairs
Therefore, the assertion is correct
The average velocity, vₐ = (Total distance traveled, d)/(Total time taken, t)
Given that the distance, 'd', covered in running up the stairs by both persons is the same, and the time it takes them to complete the distance, 't', is also the same, we have;
The average velocity of the person with the greater mass m₁ is the same as the average velocity of the person with mass, m₂
Therefore, the reason is wrong
The answer is that the assertion is correct, but reason wrong
