Change in direction, slowing down, and speeding up are all CHANGES of velocity, and THAT's called acceleration.

Constant velocity isn't a change of velocity, so it isn't called acceleration.

Mason notices that his boat sinks lower into the water in a freshwater lake than in the ocean. What could explain this?

suter [353]

Answer

D. Salt water is denser than freshwater.

Explanation

A boat is able to float on water because it experiences an upthrust upwards.

The magnitude of the upthrust depends on the density of the liquid.

When the liquid is denser the boat will experience a great upthrust as compared to when in a less dense liquid.

If the boat sinks lower in the freshwater than in salty water, then Salt water is more dense than freshwater.

At high noon, the sun delivers 1150 w to each square meter of a blacktop road. if the hot asphalt loses energy only by radiation

Pie

Stephen`s Law:
P = (Sigma) · A · e · T^4
P in = P out
e = 1 for blacktop;
1150 W = (Sigma) · T^4
(Sigma) = 5.669 · 10 ^(-8) W/m²K^4
T^4 = 1150 : ( 5.669 · 10^(-8) )
T^4 = 202.875 · 10^8
$T = \sqrt[4]{202.857 * 10 ^{8} }$
T = 3.774 · 10² = 377.4 K
Answer: Equilibrium temperature is 377.4 K.
