I believe they would electron rate would slow down and the molecules would shrink.
I am almost positive that this is correct. I hope it helps!
Answer:
30%
Explanation:
Efficiency = useful work / heat absorbed x 100
= 120/400 x 100
= 0.3 x 100
= 30%
Answer: 40
Explanation:
= 34 + 5 * 1.2465
= 40.2325
= 40
The number of significant figures in the answer should be the same as the number with the least number of significant figures that any of the digits in the equation have.
32 has 2 significant figures so the answer has to be 2 significant figures which is 40.
The space between them is shrinking at (60+40)= 100 mph. It started out being 120 miles. To shrink to zero will take
(120 miles) / (100 mph) = 1.2 hours
That's 1 hour and 12 minutes.
Answer:
(a) Current flowing through truck battery is 180 A
(b) Time taken in calculator is 333.33 s
Explanation:
(a) Given:
The charge on the truck battery,q = 720 C
Time, t = 4.00 s
Consider I be the current flowing through truck battery.
The relation between current, charge and time is:
I = q/t
Substitute the suitable values in the above equation.

I = 180 A
(b) Given:
The charge on the calculator,q = 7.00 C
The current flowing through calculator, I = 0.3 mA = 0.3 x 10⁻³ A
Consider t be the time.
The relation between current, charge and time is:
t = q/I
Substitute the suitable values in the above equation.

I = 333.33 s
