Very very roughly, an Earth month.
The Sun isn't solid, so it doesn't all have to rotate at the same rate. Different latitudes actually rotate at different speeds. One complete rotation is about 24 days at the Sun's equator, but 35 days near the poles !
Answer:
b, the fastest the car has traveled out of those options is 4-5 seconds.
Explanation:
The power delivered by the motor lift in elevating the 10 passengers at the speed of 16.8 m/s is 205800 Watts
<h3>What is power? </h3>
Power is simply defined as the rate at which energy is consumed. It can be expressed mathematically as
Power (P) = Force (F) × velocity (v)
P = Fv
<h3>How to determine the force </h3>
- Mass (m) = 1250 Kg
- Acceleration due to gravity (g) = 9.8 m/s²
F = ma
F = 1250 × 9.8
F = 12250 N
<h3>How to determine the power </h3>
- Velocity (v) = 16.8 m/s
- Force (F) = 12250 N
P = Fv
P = 12250 × 16.8
P = 205800 Watts

Answer:
The correct answer will be-
1. Allows scientists to replicate experiments
2. Tests only one variable at a time
3. Plans how to record data so they can be published
Explanation:
A scientific experiment is performed to test the hypothesis which represents the limited explanation of the phenomenon.
The experiment is designed in a way that it test one variable at a time like the growth of plants. The experiment must be designed in a way that it can be replicated to reduce the error and repeated by other scientific persons to support the experiment. The design includes the plan for recording the results as it is one of the steps of the scientific method.
Thus, the selected options are the correct answer.
Controlled experiment is the type of experiment that involves changing only one variable at a time. Controlled experiment is subtly defined as an experiment which holds everything constant except one particular variable. This type of experiment allows only one variable to ever change at a given time

Answer: The Big Bang theory</h2>
Explanation:
The Big Bang theory explains that billions of years ago, before the current universe was born, matter was concentrated in an infinitely small and highly dense point. Then, a large explosion caused this matter to expand in all directions, creating the universe we now know (including space and time).
In addition, this theory explains that our universe still continues its expansion process.
