Muttered is the same thing like mumble.
It's like when you are speaking and no one couldn't hear what you said.
So Muttered is when you say something low .
Answer:
Explanation:
height lost h = 300 sin60
= 259.8 m .
gravitational potential energy = mgh
= 5000 x 9.8 x 259.8
= 1273 x 10⁴ J
Kinetic energy
= 1/2 mv²
= .5 x 5000 x 60²
= 900 x 10⁴ J
there is loss of kinetic energy = 373 x 10⁴ J.
This loss in energy is due to kinetic friction that came into action when the sled slipped downwards.
The lost energy is converted into heat energy or thermal energy.
The car is not moving,or either it is going backwords
Synodic month, also known as a lunar month.
Answer:
Explanation:
The formula for this, the easy one, is
where No is the initial amount of the element, t is the time in years, and H is the half life. Filling in:
and simplifying a bit:
and
N = 48.0(.0625) so
N = 3 mg left after 12.3 years
