A decrease in velocity also causes a decrease in frequency and wavelength because if we manipulate the equation: v = f × wavelength, we can see that:
f = v / wavelength
wavelength = v / f
So in both cases the velocity is on the top. If the velocity decreases by a half for example then the wavelength and frequency will both decrease by a half because the velocity is proportional to the two values.
Answer:
B - A
Explanation:
For the combination of 2 vector to due southwest, 1 vector must due south and the other vector due west. Since vector B is already due west, vector A should due south. As vector A is already due north, vector -A would due south. So the combination of B + (-A) or B - A should points southwest
280 nitrous times the miles at 3800 rides per minutie equals the power in watts is 5 seconds to go 100 miles per hour.the power in horsepower is 4 seconds to get to 110 miles per hour.
Answer:
False
Explanation:
The torque exerted by a force is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the pivot
is the angle between the directions of F and d
We see that the magnitude of the torque depends on 3 factors. In this problem, we have 2 forces of equal magnitude (so, equal F). Moreover, one of the forces (let's call it force 1) acts farther from the pivot than force 2, so we have
However, this does not mean that force 1 produces a greater torque. In fact, it also depends on the angle at which the force is applied. For instance, if the first force is applied parallel to d, then we have
and the torque produced by this force would be zero.
So, the statement is false.
Explanation:
to find the theoretical velocity Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .(s=d/t) and to find the actual velocity use this formulae
h=v0*t+ 1/2 at^2
