Answer:
(2 ^2 ⋅3⋅7x 12 )
Step-by-step explanation:
#1. 720 Nm
Work = force x distance
Work = 80N x 9m = 720 Nm
#2. 90J
Assume no energy lost in the process,
<span>Kinectic energy=(80N - 70N) x 9m
= 90J
#3. 630J
Heat energy = work - kinetic energy
Heat energy = 720J - 90J
= 630J</span>
Answer:
true
Step-by-step explanation:
The left side 9 is greater than the right side 3, which means that the given statement is always true.
Answer:
The planet's speed is 18,950,000 km per 940 days
which equals
20,159.5744680851 kilometers per day
Dividing that by 24 gives us the planetary speed in km / hour which is
839.982269503546 kilometers per hour.
I have no idea what 3sf means so I can't answer that.
Step-by-step explanation:
To find how much it went up/down by, you do an equation. In June, it went up by 1.4%. That's a positive number. Down by 4.87 in July (negative), up 3% in August (positive), and down 1.33% in September (negative).
So the equation would be, 1.4-4.87+3-1.33
That gives you the answer of -1.8.
In conclusion, it fell over the four months, by -1.8%.
