Potential energy = (mass) x (gravity) x (height)
1,568 J = (40 kg) x (9.8 m/s²) x (height)
Divide each side
by 392 Newtons: Height = (1,568 N-m) / 392 N
= 4 meters .
Answer:
Explanation:
The two triangles are similar what is the length of DE
Answer: The area of the parking lot is 14,400 meters squared.
Explanation:
We have the dimensions of the parking lot.
60m by 240m
The units used here are meters.
Now, if we want to know the area of the parking lot is equal to the product between the length and the width:
A = 60m*240m = 14,400 m^2
The area of the parking lot is 14,400 meters squared.
Answer:
A. When moving towards a high pressure center the pressure values increase in the equipment
B. This area is called high prison since the weight of the atmosphere on top is maximum
Explanation:
A) A high atmospheric pressure system is an area where the pressure is increasing the maximum value is close to 107 Kpa, the other side as low pressure can have small values 85.5 kPa.
When moving towards a high pressure center the pressure values increase in the equipment
B) This area is called high prison since the weight of the atmosphere on top is maximum
in general they are areas of good weather
Answer : The number of electrons transferred are,
Explanation :
First we have to calculate the charge on electron.
Formula used :
where,
Q = charge on electron = ?
I = current = 300 A
t = time = 0.250 s
Now put all the given values in the above formula, we get:
Now we have to calculate the number of electrons are transferred.
Formula used :
where,
n = number of electrons transferred = ?
Q = charge on electrons = 75 C
e = charge on 1 electron =
Now put all the given values in the above formula, we get:
Thus, the number of electrons transferred are,
