Ocean currents are formed by a type of heat transfer that is convection
Explanation:
In the velocity triangle in the attachment we have
w = velocity of raindrop relative to ground.
v1 = 25 m/s, velocity of the car (going north) relative to ground.
u1 = velocity of raindrop relative to car
w = vector sum of u1 and v1
v2 = 25 m/s, velocity of the car (going south) relative to ground.
u2 = velocity of raindrop relative to car (vertically down)
w = vector sum of u2 and v2
from the figure we can write
= 64.08 m/s
now, we can calculate w as resultant of v2 and u2
w =
w= 68.7 m/s
also, direction of w theta = arctan(v2/u2) = 21.3 °
Answer:
ou have I=200mA, E=40J, t=30s, and you want to find the voltage drop.
First, you should know that P=V⋅I , so V=PI
Second, you have the amount of energy converted in a certain amount of time, so E=P⋅t
So, find the power and use it to find the voltage drop.
this works , but i thought energy was defined by W = P * t whitch would then be P = W/t
Period of months where the weather is the coldest and the days are the shortest.
To solve this problem we will use the concepts related to the resulting Vector Force product of two components, that is,
If we take the Force of 50 N as the force in the X direction and the Force of 40 N in the Y direction we will have to:
Finally, since Newton's second law, acceleration can be determined as
Therefore the resultant magnitude of the acceleration of the object is
