The answer is C : 7.68 × 10 3 m/s

8.7 m/s2 = (5.98 * 10 to the 24th power) - this is the mass of earth * (6.67 * 10 to the -11 power) - this is the gravitational constant / v squared = ans (6.77 * 10 to the 6th power

Then do v squared divided by 6.77 * 10 to the 6th power when you calculate it would be 7.68 × 10 3 m/s

A load of 1 kW takes a current of 5 A from a 230 V supply. Calculate the power factor.
Pachacha [2.7K]

Answer:

Power factor = 0.87 (Approx)

Explanation:

Given:

Load = 1 Kw = 1000 watt

Current (I) = 5 A

Supply (V) = 230 V

Find:

Power factor.

Computation:

Power factor = watts / (V)(I)

Power factor = 1,000 / (230)(5)

Power factor = 1,000 / (1,150)

Power factor = 0.8695

Power factor = 0.87 (Approx)

How are weather satellites and weather stations similar?
alexandr402 [8]
<span>Weather satellites and weather stations are similar, because they both have the same purpose. They are used to help predict future weather as well as as current conditions. The satellites are viewing the weather from a distance at a large scope, but stations are using data they collect on earth to help with the same task.</span>
