The quantities that are not constant in uniform circular motion are :
1. Angular Velocity , the direction keep changing in angular velocity so it's not constant
2. Angular position, theta will keep on changing until it reach 360
3. Direction of centripetal acceleration
hope this helps
Answer:
Step-by-step explanation:
square of 15 + square of x = square of 21
225 + square of x = 441
441 - 225 = 216
x = 216
Answer:
1 - c
2 - A
Step-by-step explanation:
Hey There!
So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume
Remember to find the volume we use the equation
V = length x width x height
so we just plug in the values
v = 2.6 x 2.1 x 3.9 = 21.294
the closest is 20 so C is your answer
For the second one we are given a triangular prism
and they want us to find the volume

b = base (10.3)
l = length (4)
h = height (7)
7x4=28
28x10.3=288.4
then we divide by 2
288.4/2=144.2
so your selected answer is correct
Answer: 37.5
Step-by-step explanation:
75 divided by 2
It is an acute triangle since all the sides are less than 90 degrees (it's also equilateral)
