The car should have less kinetic energy.
They are both going the same speed, but the truck is bigger and heavier. The more mass an object has, the more kinetic energy it has. There is more mass being moved, so it makes more kinetic energy. The car does not have as much mass, so it makes less kinetic energy compared to the truck.

Good luck with the rest of your test or quiz :)

A hiker determines the length of a lake by listening for the echo of her shout reflected by a cliff at the far end of the lake.

Nataliya [291]

To solve the exercise it is necessary to take into account the definition of speed as a function of distance and time, and the speed of air in the sound, as well

$v=\frac{d}{t}$

Where,

V= Velocity

d= distance

t = time

Re-arrange the equation to find the distance we have,

d=vt

Replacing with our values

$d= (343)(3.7)$

$d= 1269.1m$

It is understood that the sound comes and goes across the entire lake therefore, the length of the lake is half the distance found, that is

$L_{lake} = \frac{d}{2}$

$L_{lake} = \frac{1269.1}{2}$

$L_{lake} = 634.55m$

Therefore the length of the lake is 634,55m

We have a radioactive isotope called RI which has a half-life of 12 million years. A geologist has used radiometric dating and d

dedylja [7]

Answer:

3

Explanation:

half life, T = 12 million years

total life, t = 36 million years

Let n be the number of half lives.

n = Total life / half life

n = 36 / 12 = 3

So, the number of half lives are 3.
