Answer: 22.11 ohms
Explanation:
Potential difference(v)=420V
Current(I)=19.0 amp
Resistance(r)=?
r=v/I
r=420/19.0
r=22.11 ohms
Answer:
<h3>The answer is 1400 J</h3>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
PE = 20 × 10 × 7
We have the final answer as
<h3>1400 J</h3>
Hope this helps you
Answer: 1- Issac Newton is the man who discovered gravity. he is important because he found out why everyone was pulled down to the ground. this would later hepl disprove the flat earth theory.
2- Id on't know the vocab words. do those. it'll be the quickest.
3- wieght is how much is being pulled to the ground. mass is how big you are. A pound of rocks and a pound of feathers wiegh the same, but the mass of a pound of feathers will be much greather, as it takes much more feathers to equal a poud than rocks.
Explanation: CHEACK ALL SPELLING!!!! I can't spell that well and my g key doenst like working.
Explanation:
Momentum before collision:
(2 kg) (4 m/s) + (5 kg) (-3 m/s) = -3 kg m/s
No external forces act on the balls, so momentum is conserved. Therefore, momentum after collision is also -3 kg m/s.
