As we know that, f=ma where
f= net force
m=mass of body
a=acceleration
Substitute m and a in the formula and you will get the answer
Answer:
Mass of a body is define as the total quantity of matter contained in it .
Density is the mass per unit volume in any object .
A physical properties is an any property that is measurable , whose value describe a state of a physical system
Forecasters must consider a large number of variables that affect the path of the storm.
This makes it difficult to create computer-based models because all of these variables are hard to incorporate.
Answer:
1.4584 kg
Explanation:
Time period of a physical pendulum is given by 
Here f=0.290 so 
Mass =2.40 kg
d=0.300 m
g =9.8 m
So 
kg-
So the moment of inertia of the pendulum about the pivot point will be 1.4584 kg-
Answer:
35%
Explanation:
Given data
Amount of energy transferred (Input) = 270J
Amount of energy converted to sound (Output)= 94.5J
Efficiency = output/input*100
Efficiency= 94.5/270*100
Efficiency=0.35*100
Efficiency=35%
Hence the efficiency is 35%
