Answer:
Nearest, the revolutions per minute will be 29.
Explanation:
Given that,
Radius of circle = 1 m
Acceleration a =g
We know that,
Angular frequency is defined as,
Where, n = number of revolutions in one second
We need to calculate the revolutions in one second
Using formula of centripetal acceleration
Put the value of a and ω
Put the value into the formula
We need to calculate the revolutions per minute
Using value for the revolutions per minute
Hence, Nearest, the revolutions per minute will be 29.
Answer:
0.130
Explanation:
From the given data, the coefficient of static friction for each trial are:
1. 0.053
2. 0.081
3. 0.118
4. 0.149
5. 0.180
6. 0.198
The sum of the coefficient of static friction = 0.053 + 0.081 + 0.118 + 0.149 + 0.180 + 0.198
= 0.779
So that;
the average coefficient of static friction =
=
= 0.12983
The average coefficient of static friction is 0.130

There would still be 48 atoms. But 24 would have thrown off
particles from their nucleuses, and only 24 would still be radioactive.</span>
Answer:
Explanation:
The expression for the trigonometric function is :
L(t) = A (cos (B(t - C)))+ D ----- equation (1)
where ;
A = 0.125
D =
D = 0.125
Period of the lunar cycle = 29.53
Then;
Also; we known that December 25 is 7 days before January 1.
Then L(-7) = 0.025
Plugging all the values into trigonometric function ; we have:
Answer:
force = mass * acceleration
therefore the SI unit is kg*m/s2 or newton's
it's a vector quantity because it has both direction(acceleration) and size (mass)
