-- Find the mass of all the pieces before the reaction.
-- Find the mass of all the pieces after the reaction.
-- Find the difference . . . (mass before) minus (mass after)
-- If any mass is missing, either you lost track of it, or else
it was converted to energy.
How much energy ?
(the missing mass) times c² .
Answer:
20 kg
Explanation:
remember the equation f=ma.
100 N=force
5 m/s2= acceleration
so you need to divide force by acceleration: 100 N/ 5 m/s2= 20 kg, to get the mass.
Answer:
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
Explanation:
Watt is a unit for power that is equivalent to Joules per second (J/s). Therefore, to figure out the energy burnt up during an activity, first we need to know how long (in seconds) that activity took.
1- Running
V = 10.0 km/h
d = 5.50 km
t = 5.50/10 = 0.55 h = 0.55(h) *60 (min/h) *60(s/min) = 1,980 s
2- Walking
V = 3.0 km/h
d = 5.50 km
t = 5.50/ = 1.83333 h = 1.83333(h) *60 (min/h) *60(s/min) = 6,600 s
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
Answer:
D-Andes Mountains
Explanation:
Convergent boundaries are places where two tectonic plates are moving against eachother and collide, causing faults and mountains, from the options the only feature that us caused by convergent plate boundaries is the Andes Mountains that are created by the collision of the Nazca plate and the Southamerican plate, this collision created the Andes Mountains in Peru.
