Answer:
F = 683.8 N
Explanation:
The gravitational force of attraction between the Earth and the student is given by Newton's Law of Gravitation as follows:
where,
F = Force = ?
G = Universal gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²
m₁ = mass of Earth = 5.98 x 10²⁴ kg
m₂ = mass of student = 70 kg
r = distance between Earth and student = 6.39 x 10⁶ m
Therefore,
<u>F = 683.8 N</u>
Answer:
Therefore, the answer is: Option A.
Explanation:
- The average speed is defined as the total distance traveled by an object divided into the time that it takes for the object to travel that distance.
- Average speed is a scalar quantity, which means that it can be represented using a number with no need of specifying a direction. Since the total distance is a positive value, then average speed is always also a positive value.
From the options, the statement "average speed includes both rate of motion and its direction" is false.
Answer:
Net Force
Explanation:
Net Force is all i have to say to you BYE
If you can please make me brainiest
The answer is the second option "watt." Watt is the unit of power measured by one joule per second. Watts are a amount of electrical power and measured by the rate of energy transfer between two things.
Hope this helps.
