True . Your statement is correct
water vapor that has condensed and covers the ground in the morning
Answer:
a) 
b) Efficiency=76.77%
Explanation:
a)
In order to solve this problem, we can use the following formula:

the problem provides us with all the necessary information so we can directly use the formula:


b) In order to find the efficiency, we can use the following formula:

so we get:

Efficiency=76.77%
If the force is 3,000 N and the acceleration is 2 m/s/s. The mass of the car is 1,500 grams (or whatever unit of mass or weight is used in the answer- pounds, kilograms e.t.c.).
Answer:
3.42N
Explanation:
*not too sure bc i left my physics notes at school so it might not be 100% accurate :p*
Use the equation: F = (GMm)/(r^2)
F = force of gravity
G = gravitational constant (6.7x10^-11)
M = mass1 (2.5x10^30kg)
m = mass2 (1kg)
r = radius (7000m)
Plug it in: F = ((6.7x10^-11)(2.5x10^30)(1)) / (7000^2)
F = (1.675x10^20) / (4.9x10^7)
F = 3.4183673x10^12
F = 3.42N
