Answer:

B: The air pressure decreases

Explanation:

Pressure at any given height in the atmosphere is the total weight of the air above a unit area at any height.

Increase in elevation leads to decrease or lesser air molecules above a given surface than a similar surface at lower levels.

Answer:

B. the air pressure decreases

Explanation:

As elevation increases, there is less overlying atmospheric pressure mass, so that atmospheric pressure decreases with increasing elevaton.

You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizont
Scilla [17]

Answer:

R_{max} = 51.84 m

Explanation:

When we shoot the dart upwards the time taken by the dart to go straight up and again come back is given as

t = 4.6 s

here we can say

\Delta y = 0 = v_i t + \frac{1}{2}at^2

0 = v_i t - \frac{1}{2}(9.8)t^2

put t = 4.6 s then we have

v_i = 22.54 s

Now in order to find the maximum range we can say

R = \frac{v^2 sin2\theta}{g}

so in order to have maximum range we can say

\theta = 45 degree

R_{max} = \frac{v^2}{g}

R_{max} = \frac{22.54^2}{9.8}

R_{max} = 51.84 m

A brick of mass 4 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 3 cm. The spring is t
jeka57 [31]

Answer:

Explanation:

Let s be displacement from equilibrium position . Restoring force

m d²s / dt² = - k s

d²s / dt² = - k /m  s

Put k /m  = ω

d²s / dt² + ω² s = 0

The solution of this differential equation

= s = A cosωt

Now when t = 0 ,  s = 2 cm

A =  2 cm

Putting the values we have

2 = A cos 0

A = 2 cm

s ( t) = 2 cos ωt

How can a megaphone used by a cheerleader allow people on the opposite side of a field to hear her better?
Goshia [24]
The megaphone is cupping the area around her mouth and it is like with your hands, if you cover around them the noise will be louder. It is because it is hollow and there isn't anything to block the noise through the megaphone.
