In general, the surface of Mercury is similar to the Moon (i.e. heavily cratered due to a lack of a heavy atmosphere to erode away primordial impacts). However, there are some key differences: 1) There are few maria on Mercury and they are small.
Answer:
They are rechargeable
They have a longer life span
They are reusable
Explanation:
Lead acid accumulators and leclanche cells are types of electrochemical cells.
Leclanche cells are primary cells. Primary cells produce chemical reactions through which the electric current generated is irreversible.
Lead Acid Accumulators are secondary cells in which electric current generated is reversible.
This makes lead acid accumulators reusable, more durable and they have a longer life span.
Answer:
The answer is 3.111111.
Explanation:
It runs 28 m in the first 9 s, and 28 divided by 9 equals 3.1 and the one goes on forever.
Answer:
For object A
m = 5 kg , v= -11 j
For B object
m = 6 kg , v= 5 i +8.7 j
For object C
m = 10 kg , v= -10 i
We know that
Linear momentum P= m v kg.m/s
a) A and C
Momentum in y direction
Py=- 5 x 11 j= - 55 j kg.m/s
Momentum in x direction
Px=- 10 x 10 j= - 100 i kg.m/s
b) B and C
Momentum in y direction
Py=6 x 8.7 j= 52.2 j kg.m/s
Momentum in x direction
Px=( 6 x 5 - 10 x 10 ) i = - 70 i kg.m/s
c) A ,B and C
By using data of a and b
Momentum in y direction
Py= 6 x 8.7 - 5 x 11 j= -2.8 j kg.m/s
Momentum in x direction
Px= 6 x 5 -10 x 10 i = -70 i kg.m/s
