Answer:
The work done is zero
Explanation:
No work is performed or required in moving the positive charge from point A to point B
Answer: Only 2 and 3
Explanation:
2.) Wavelength has an inverse relationship with wave frequency when wave speed remains constant.
3.) Wave speed is directly related to the product of wavelength and frequency.
V = F(λ)
Where
V = wave speed
F = wave frequency
(λ) = wavelength.
M = 45.0 g in Kg 0.045 Kg
speed = 75.0 m/sec
Δp = m * speed
Δp = 0.045* 75.0
Δp = 3.375 kg.m/s
hope this helps!
<span>Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the troposphere,
the air pressure starts to decrease. <span>Below the atmosphere is the hydrosphere. This is
where all liquid forms are located. And since the seawater has a greater mass
than air, it has the greatest pressure. The answer is true.</span></span>
