9. An object which is in circular motion (moving along a circle) is said to be accelerating because it changes it's direction constantly even if it is moving with a constant speed. cuz acceleration is change in either magnitude or direction of an object with respect to time.
therefore, it's still acceleration as change in direction with time.
10. Average speed of an object can be calculated by dividing the total distance covered by an object by time taken to cover that distance.
i.e
it can be re- arranged to find the distance as :
11. speed = 20 m/s : conversion into km/h
distance covered : 4 km = 4000 m
time taken = 200 seconds
12. let's use the first equation of motion to find the acceleration :
The required equation for the sine function can be written as; V = 120sin120πt
<h3>What is a sine function?</h3>
A sine function is a regular repeating function. We know that the voltage is represented using a sine function of the general form V= V-o sin2πft
Hence;
f = 60 cycles per second
V-o = 120 volts
So from the values that we have stated above;
V = 120sin120πt

Answer:
1. the rocks at the bottom of the aquarium
2.the fish and maybe the plants (if you use live plants)
3. fish interact with there no living things like how one would hide in the grass or something like that.
4. decorations (like a cave or fake house, tho the aquarium its self is a home)
5.they would die, and rot.
Explanation:
rocks are nonliving
fish are living things and so are plants
fish can hide in the plants
the fish can "live" in the decorations, but the aquarium itself is its home.
if something reaches the end of its life span it dies.
Answer:
a solar eclipse occurs when the moon passes in front of the sun,blocking it out partially or completely. the eclipse results in parts of the earth being covered in the shadow of the moon. a lunar eclipse occurs when the moon passes directly behind earth and into its shadow.
Explanation:
Answer:
14.112 mV
Explanation:
L = 16 m, v = 21 m/s, B = 42 μ T = 42 x 10^-6 T
The formula for the induced emf is given by
e = B x v x L
e = 42 x 10^-6 x 21 x 16 = 14.112 x 10^-3 V = 14.112 mV
Thus, the induce emf is 14.112 mV.
