Answer:
D
Explanation:
Now we know that Force is the rate of change of momentum meaning
F= mv/t
But
mv/t = Ke
v/t = ke/m
a= ke/m
Where a is acceleration
K is constant of proportionality of tension on a spring
e is the extension substended by a string.
From the formula of acceleration we can see that as mass decreases acceleration increases so we can see that m = 1
We would have a maximum value of acceleration.
-The Answer is A Ultraviolet-
Explanation: UVA (Ultraviolet) rays can cause serious damage to your skin.
Answer:
11250 N/C
Direction: 0 deg counterclockwise from positive x-axis
Explanation:
= magnitude of charge on each particle = 5 μC = 5 x 10⁻⁶ C
= distance of each particle from center of circle = 2 m
= Magnitude of electric field at the center by each particle
Magnitude of electric field at the center by each particle is given as
inserting the values
From the diagram , we see that being equal and opposite, the electric fields due to charge q₁ and q₃ cancel out.
So net electric field at center is only due to charge q₂ direction towards positive x-direction
So
= Resultant electric field = 11250 N/C
Direction: 0 deg counterclockwise from positive x-axis
4 blue = 3 white
x blue = 12 white?
Cross multiply
48 = 3x
x = 16 blue
Another way to do this is figure how many times 3 whites go into 12 whites.
That's 4 times.
So 4 blue x 4 = 16 blue
An action-reaction pair shows the direct relationship two objects have <u>directly</u> on each other. Therefore, the correct answer is C. The Moons gravity pulls on you, and your gravity pulls on the Moon because it is moon gravity-person person gravity-moon.
Choice A would be made correct if it was you pull on a drawer and the drawer pushes on you OR the table pushes on the ground and the ground pushes on the table.
Choice B would be made correct if it was a computer sits on a table and the table pushes up on the computer.
Choice D would be made correct if it was an eraser sits on a shelf and the shelf pushes up on the eraser OR the wall pushes on the shelf and the shelf pushes against the wall.
Hope this helps!!
