Answer:
Explanation:
Over the course of a year, the angle of tilt does not vary. In other words, Earth's northern axis is always pointing the same direction in space. ... But the orientation of Earth's tilt with respect to the sun – our source of light and warmth – does change as we orbit the sun.
I got this out my pysics book so it should be correct.
Answer:
a = 1.02834008 m/s2
Explanation:
given data:
initial velocity u = -1.03 m/s
time t = 2.47 s later
final velocity v = 1.51 m/s
average acceleration is given as a
putting all value to get required value of acceleration:
= 1.02834008 m/s2

Answer:
You can drink 18 drinks and 1.38 dollars left with you.
Explanation:
1 drink cost 1.59 dollars
You have 30 dollars with you.
Number of drinks in 30 dollars =
Number of drinks in 30 dollars = 18
From division 1.36 remains as remainder so, 1.38 dollars left with you.
ANSWER:
300 J
STEP-BY-STEP EXPLANATION:
To know the work required, we must calculate the work in both cases, the difference would be the amount of work necessary for the speed to increase. The work done is the same as the amount of energy increase. The formula for kinetic energy is:
We calculate in each case:
We calculate the difference between the two to find out the work required:
The work required is 300 J
