Answer:
The magnitude will be "353.5 N". A further solution is given below.
Explanation:
The given values is:
F = 500 N
According to the question,
In ΔABC,
⇒ 
⇒ 
then,
⇒ 
⇒ 
Now,
The corresponding angle will be:
⇒ 
⇒ 
⇒ 
Aspect of F across the AC arm will be:
= 
On putting the values of F, we get
= 
= 
Component F along the AC (in magnitude) will be:
= 
= 
= 
It was <em>(1/2) (Net force on the cart) m/s²) </em>.
Answer:
Plug in the given values and solve for the final velocity. Remember, when the ball is on the ground it has a height of zero.
Explanation:
Answer : The correct option is, (a) No. Potatoes will be warmer.
Explanation :
Formula used :

where,
Q = heat taken
m = mass of substance
c = specific heat of substance = ?
= change in temperature
As we are given that the potatoes have a specific heat of
and raisins have a specific heat of
. That means higher the value of specific heat the more heat taken by the substance (more warmer will be the substance). So, the potatoes will be more warmer as compared to raisins.
Hence, the correct option is, (a) No. Potatoes will be warmer.
Explanation:
potential energy = mass × gravity force × height
=20 × 10 × 25
= 5000 joules
