Answer:
10000W
Explanation:
work=1000*200=200000
then
P=work/time=200000/20=10000W
Answer:
B. Chemical changes involve the formation of a new substance.
Explanation:
They can both release energy, both can be measured, and chemical changes can be caused by oxygen, so I believe it would be B.
The correct option is: Option (D) 1.0T Out of the page.
Explanation:
The formula for the induced emf in the wire = ε = Blv
ε = Potential difference = 1.0 V
v = speed of the wire = 10 m/s
l = length of the wire = 10cm = 0.1 m
B = magnetic field = ?
Plug in the values:
B = ε/lv = 1/(0.1*10) = 1 T (And according to the right hand rule it should be out of the page.)
Well as you've seen before most likely, an apple can fall right off a tree, and stay perfectly fine. its all dependent on the variables. What angle is the apple falling at? Whats the speed, height, even the size of the apple? We must take into aware anything can happen, but its all behind the variables.

P.S Fact Check with the second person who just answered
You cannot convert newtons to kilograms, or pounds to kilograms,
or kilograms to pounds or newtons.
Newtons and pounds are units of FORCE. Kilogram is a unit of MASS.
If an object weighs 44 newtons on Mars,
then its mass is about 13.5 kilograms
If an object weighs 44 newtons on the Moon,
then its mass is about 27.2 kilograms.
If an object weighs 44 newtons on Earth,
then its mass is about 4.5 kilograms.
