Answer:
Explanation:
Given that
We know that from continuity equation
So
Now from energy equation
Q=6.17 x 0.08
Answer:
Force = 24.5 Newton
Explanation:
Given the following data;
Mass = 3.50 kg
Initial velocity, u = 3 m/s
Final velocity, v = 17 m/s
Time, t = 2 seconds
To find the force;
First of all, we would determine the acceleration of the object using the formula;
Acceleration = (v - u)/t
Acceleration = (17 - 3)/2
Acceleration = 14/2
Acceleration = 7 m/s²
Now, we can find the force using the formula;
Force = mass * acceleration
Force = 3.5 * 7
Force = 24.5 Newton
The chemical change is are to water breaking down into hydrogen and oxygen.
Answer is D.
Answer:
v= 300 m/s
Explanation:
Given that
altitude ,h= 4500 m
The mass ,m = 3 kg
Lets take acceleration due to gravity , g= 10 m/s²
The speed before impact at sea level = v
Initial speed ,u = 0 m/s
We know that
v²=u²+2 g h
v=final speed
u=initial speed
h=height
Now by putting the values in the above equation
v² = 0²+ 2 x 10 x 4500
v²=90000
v= 300 m/s
Therefore the speed at sea level will be 300 m/s.
The relationship between work and energy is that work can transfer energy between objects and cause a change in the form of energy.
<h3>What is energy?</h3>
Energy is simply defined as the ability to do work.
Energy possessed by any object or matter enables it to do work of various forms.
Energy can be transferred from one object to another. Also, energy can be transformed into various forms.
Therefore, the relationship between work and energy is that work can transfer energy between objects and cause a change in the form of energy.
