Answer:
a = 0.45 m/s²
Explanation:
The given question is ''Calculate the acceleration that produces a force of 40 N on a body with 88 kg of mass".
Given that,
Force, F = 40 N
Mass of the body, m = 88 kg
The net force acting on the body is given by :
F = ma
Where
a is the acceleration of the body

So, the required acceleration is 0.45 m/s².
Acceleration is the way the motion is changing.
Answer:
a) 
b) 
c) 
Explanation:
Given:
- voltage of the battery,

- energy storage capacity of the battery,

- speed of the car,

a)
power drawn by the car, 
<u>Now the Current delivered to the motor:</u>
we the relation between the power and electrical current,



b)
<u>Distance travelled before battery is out of juice:</u>
we first find the time before the battery runs out,



Now the distance:



c)
When the head light of 55 W power is kept on while moving then the power consumption of the car is:



<u>Now the time of operation of the car:</u>



<u>Now the distance travelled:</u>



Answer:
T₂ = 305.17 K
Explanation:
Given that,
Heat, Q = 6000 J
Mass, m = 200 gram
Initial temperature, T₁ = 25° C
We need to find its final temperature. Let it is T₂.
We know that,

Where
c is the specific heat of water, c = 4.18 J/g°C
So,

So, the final temperature is equal to 305.17 K.
