Answer:
<h2>6.67 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>6.67 m/s²</h3>
Hope this helps you
Explanation:
A) use the formula:
B) use the formula:
with angular velocity u calculated in A)
Answer:
Current is in phase with voltage in a resistive circuit. Note that the wave form for power is always positive, never negative for this resistive circuit. This means that power is always being dissipated by the resistive load, and never returned to the source as it is with reactive loads.Explanation:
D = m / V
11.3 = 282.5 / V
V = 282.5 / 11.3
V = 25 cm³
Answer : Infrared rays have a shorter wavelength than radio waves.
Explanation :
The wavelength of Infrared rays is 700 nm – 1 mm
The wavelength of X- rays is 0.01 nm – 10 nm
The wavelength of UV rays is 10 nm – 400 nm
The wavelength of radio waves is 1 meter – 100,000 km
The wavelength of gamma rays is less than 0.01 nm
So, from the above data it is clear that the wavelength of the infrared rays have a wavelength shorter than the radio waves.
Hence, the correct option is (C) " radio waves ".
