Answer:
The answer is 30 min
Explanation:
t = s/v
v = 70 m/min, s = 2100 m
t = 2100/70 = 30 min.

The components of the resultant will be: (18, 12)
In order to find the magnitude you have to apply the Pythagorean theorem:
√(18² + 12²) = √468 = 21.6
Therefore, the magnitude of the resultant vector is 21.6
The direction is given by the formula:
α = tan⁻¹(v_y / v_x)
= <span>tan⁻¹(12/18)
= 33.7°
Therefore, the direction will be 33.7° from the x-axis.</span>
True. Free trade means they can't refuse to give you cash for a check. If you want the check deposited to an account, that's another story.
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.
Gravity is a force because it pulls down on objects.
