Answer: time=4 hours

Explanation:

formula:

speed = $\frac{distance}{time}$

time = $\frac{distance}{speed}$

time= x

speed = 120km/hr

distance = 480 km

x = $\frac{480 km}{120km/hr\\}$

= $\frac{48km*hr}{12km}$

cut the zeros

and remove the signs

then

$\frac{48}{12}$ = 4

therefore, time taken to deliver the shipment by trucker is 4 hours

In a parallel circuit, what’s happens to the current through each resistor when the voltage is doubled?

34kurt

Answer:

Explanation:

Voltage, V = Current, I x Resistance, R (V is directly proportional to I where R is constant of proportionality)

This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.

A wave traveling in the positive x-direction with a frequency of 50.0 Hz is shown in the figure below. Find the following values

Klio2033 [76]

Answer:

Explanation:

a. The amplitude is the measure of the height of the wave from the midline to the top of the wave or the midline to the bottom of the wave (called crests). The midline then divides the whole height in half. Thus, the amplitude of this wave is 9.0 cm.

b. Wavelength is measured from the highest point of one wave to the highest point of the next wave (or from the lowest point of one wave to the lowest point of the next wave, since they are the same). The wavelength of this wave then is 20.0 cm. or $\lambda=20.0cm$
