If you run a complete loop around an outdoor track of length 400 m in 100 s, find your(a) average velocity and (b) average speed. *
Answer:
a) 0 m/s
b) 4 m/s
Explanation:
The average velocity would end up being 0 because it is displacement over time and the displacement here is 0. However, speed is total distance over time which here is 400/100 so it is 4.

Calculate the normal force and force applied of a box that has a mass of
50kg and that is moving rightward with an acceleration of 7.2m/s^2
Heya!!
For calculate force, lets applicate second law of Newton:
[tex]\boxed{F=ma}[/tex]
Δ Being Δ
F = Force = ?
m = Mass = 50 kg
a = Aceleration = 7,2 m/s²
⇒ Let's replace according the formula:
[tex]\boxed{F= 50\ kg * 7,2 m/s^{2}}[/tex]
⇒ Resolving
[tex]\boxed{ F = 360\ N}[/tex]
Result:
The force is 360 Netwons.
Good Luck!!

I’ll give another brainlist now your going up a hill and want to maximize the force you deliver to the wheel you aren’t concerned with how many strokes you are making but you want to get as much force to the wheel as possible which gear combination would you use now and why
Answer: The biggest gear
Explanation:
Small gears allow the fastest speed but least amount of power, all the while, the bigger the gear the more power is going to be present.
If this isn't enough I already completed this assignment.

Give a description of of lower mantle
Answer:
The lower mantle is the liquid inner layer of the earth from 400 to 1,800 miles below the surface.
Explanation:
true or false. because the speed of an object can change from one instant to the next, dividing the distance covered by the time of travel gives constant speed
true. Because the speed of an object can change from one instant to the next, dividing the total distance covered by the time of travel gives. average speed.
Answer:
False.
Explanation:
Dividing the distance covered by the time would give us the average speed, not a constant speed. Constant speed exists only if the speed of an object does not change.

.. An object has a mass of 40 000 kilograms
and a volume of 5 cubic metres. What is its
density?
Answer:
8000 kg/cm^3
Explanation:
The density formula is P = M/V
Density = P = ? expressed in kg/m^3
M = mass = 40,000 kg
V = volume = 5 m^3
P = 40,000/5
P = 8000 kg/m^3
Two persons A and B are walking with speed 5 km/h and 6 km/h
respectively in the same direction. Find how far will B be from A after
2 hours.
a 6 km
b 2 km
C 5 km
d 3 km
Answer:
b
Explanation:
The relative distance can calculate by dividing the time travelled by the speed difference between points A and B. Considering that B is going more quickly than A, we substract A's speed from B's speed.
Relative Speed = Speed of B - Speed of A
Relative Speed = 6 km/h - 5 km/h
Relative Speed = 1 km/h
Now, we can calculate the relative distance traveled by B after 2 hours:
Relative Distance = Relative Speed * Time
Relative Distance = 1 km/h * 2 hours
Relative Distance = 2 km
Therefore, B will be 2 kilometers away from A after 2 hours of walking in the same direction.
