D. is the correct answer forthis question
Answer:
e. Evaporation affects land more than ocean surfaces.
Explanation:
Land warms faster than water. Since the kinetic energy of a molecule is proportional to its temperature, evaporation occurs faster as the temperature is higher. As the molecules that move faster escape, the remaining molecules have a lower average kinetic energy, and therefore the temperature of the liquid decreases.
The law of enertia I’m not sure how to spell it in sorry inertia I think
Given info is
<span>Distance= 100m and Time=10s </span>
<span>Velocity=100/10=10m/s </span>
<span>Kinetic energy= 1/2mv^2 </span>
<span>Rough estimate of mass of athlete=80kg </span>
<span>Ek= 1/2x80x10^2= 4000J </span>
The rate of change of velocity with respect to time is acceleration. When we have some period of time, mathematically we write it: a=Δv/Δt, where Δv is a change in velocity and Δt is a time interval. When we talk about an instant of time, we have a limit: a=lim Δv/Δt, where Δt→0 and we write that as a=dv/dt where dv is an infinitesimal or infinitely small change in velocity and dt is an infinitesimally or infinitely small change in the time interval. So the correct answer is: the rate the velocity is changing at a given instant is acceleration.
