Answer:
36watts
Explanation:
Data obtained from the question include:
R (Resistor) = 4 Ohms
V (Voltage) = 12V
P (power) =?
P = IV
Recall: I = V/R
P = V^2 /R
P = (12)^2 /4
P = 144/4
P = 36watts
Therefore, power is 36watts
The average power is 10 watts. What's the question ?
Answer:
The difference lies in the planets' respective magnetic fields, because while Earth's magnetism comes from within, Mars' does not. Earth's magnetism comes from its core, where molten, electrically conducting iron flows beneath the crust. Its magnetic field is global, meaning it surrounds the entire planet

thanks for question
Let's use the mirror equation to solve the problem:

where f is the focal length of the mirror,

the distance of the object from the mirror, and

the distance of the image from the mirror.
For a concave mirror, for the sign convention f is considered to be positive. So we can solve the equation for

by using the numbers given in the text of the problem:



Where the negative sign means that the image is virtual, so it is located behind the mirror, at 8.6 cm from the center of the mirror.
Answer:
B. 7.5 m/s^2
Explanation:
To find acceleration you need to subtract the final velocity by the starting velocity then divide that by the time
a= v-v/t
a= 60-0/8
a= 60/8
a=7.5 m/s^2
