The value of a scientific variable can change. (A)
Hint hint: That's why it's called a "variable". If it always remained the same, then it would've been called a "constant".
Answer:
<h2>92.86 kg </h2>
Explanation:
lThe mass of an object given only it's force and acceleration can be found by using the formula
f is the force
a is the acceleration
From the question
f = 195 N
a = 2.1 m/s
We have
We have the final answer as
<h3>92.86 kg</h3>
Hope this helps you
Answer:
The beat frequency is 30 Hz
Explanation:
Given;
velocity of the two sound waves, v = 343 m/s
wavelength of the first wave, λ₁ = 5.72 m
wavelength of the second wave, λ₂ = 11.44 m
The frequency of the first wave is calculated as follows;
F₁ = v/λ₁
F₁ = 343 / 5.72
F₁ = 59.97 HZ
The frequency of the second wave is calculated as follows;
F₂ = v/λ₂
F₂ = 343 / 11.44
F₂ = 29.98 Hz
The beat frequency is calculated as;
Fb = F₁ - F₂
Fb = 59.97 HZ - 29.98 Hz
Fb = 30 Hz
The IMA of the pulley shown is 2.
