Answer:
the total mass after chemical burn is 700 gram
Explanation:
Given data
glass mas s= 200 gram
chemical mass = 500 gram
total mass = 700 gram
to find out
what is the total mass after chemical burn
solution
we have given 200 gram + 500 gram = 700 gram
and we know here according to question that
container is sealed so total mass remain in container before burning and after burning
no air will release in seal container so
mass will be same as 700 gram
hence the total mass after chemical burn is 700 gram
1 mile = 1609.344 meters 1 hour = 3600 seconds Initial speed of the getaway car = v1 = 0 m/s (At rest) Speed at which the getaway car explodes = v2 = 120 mph = 120 x (1609.344/3600) m/s = 53.…
Answer:
quasars are massive celestrial bodies that are far or remotely placed emitting large energy radiations.
parallax is the best way of determining distances between astronomical bodies and parallaxes of stars are measured relative to a quasar to minimise the measurement error. each observations is stimulated with the basic angle variations leading to minimum uncertainty in the results as the assumptions in the measurements are as minimal as possible.
The mass of the man would remain the same…
His weight would change. Assuming the man’s weight on earth is 60N.
Since weight is a force, according to Newton’s second law, F = ma ( m = mass, a = acceleration due to gravity) First lets find the mass of the man, as it is required to find his weight on the moon.
F=ma[taking a of earth as10m/s
2
]
60=m.10[divide10onbothsides]
m=
10
60
= 6 Kg
Acceleration due to gravity on the moon is83%less than the acceleration due to gravity on earth(1.622m/s
2
).
F=ma
F=6.1.622=9.732 N
So a person weighting 60N on earth would approximately weight around 10Non the moon.
