<em>im confused hold on imma send you a link to the answer</em>Explanation:
D. The chemical potential energy of real battery decreases, it develops internal resistance and therefore the potential difference across its terminals decreases if its current increases.
Answer:
m
Explanation:
Consider the motion of the boat across the stretch from west to east direction :
= velocity of boat = 15 mph
= length of the stretch = 1.01 miles
= Time taken to reach the opposite end
Time taken to reach the opposite end is given as
h
sec (Since 1 h = 3600 sec)
sec
= speed of river = 2.04 m/s
= distance traveled downstream
Distance traveled downstream is given as
m
The apple is lifted by 1.1 m
<u>Explanation</u>:
- Given that, mgh = 2 J and mass of apple = 180g
- Step 1: convert grams to kg as work is given in SI units.
180 g = 0.18 kg
- Step 2: substitute in the formula for work done.
0.18 * 10 * h = 2
- Step 3: calculate the value of h from this formula.
h = 2/1.8
h = 1.11 m
Answer:
y=4x−20
Explanation:
The given equation is :
y+8=4(x−3)
Using distributive property at RHS.
y+8=4x−12
Taking variables to the one side and constant terms to another side.
y-4x = -12-8
y-4x=-20
or
y = 4x-20
Hence, the correct option is (c).
