Answer:
B. Longer than t s,
Explanation:
Gravitational accln on earth is 9.8 m/s^2,
and one you provided as on moon is 1.6 m/s^2
that mean on moon gr. accl. is lesser!
now the time taken on earth will be lesser cuz from the same height if you drop the object from rest!
since accln on earth is higher,the object will attain higher velocity as compare to that of on moon!

Answer:
new temperature of the tire will be 278.76 K
Explanation:
when the temperature increases, the particles will have greater kinetic energy and also the pressure will be increase for the gas particles.
so when the temperature increases, pressure will also increase and vice versa
T is directly proportional to P
T1 = initial temperature= 303 k
P1= Initial pressure = 325000 pa
T2= Final temperature= ?
P2= Final pressure = 299000 pa
mathematically
P1/T1= P2/T2
T2= P2 x T1/P1
T2 = 299000 x 303/ 325000= 278.76 k
Main Answer:
Given speed of spaceship v = 0.8c = 0.8 * 3 x 10^8 m/s
Speed of spaceship v = 2.4 x 10^8 m/s
Distance need to be travelled d = 4.3 light years
we know that 1 light year = 9.461 x 10^15 m
Distance need to be travelled d = 4.3 x 9.461 x 10^15
d = 40.6823 x 10^15 m
Time taken for the trip would elapse on a clock on board the spaceship
t = distance/ velocity
t = 40.6823 x 10^15 / 2.4 x 10^8
t = 16.95 x 10^7 sec
t = 4.71 x 10^4 hours
Explanation:
What is light year?
Light year is defined as the distance travelled by the light in one year. In a year, light travels through 300000 km per sec in the interstellar space.

Answer:
Heat flows from higher to lower temperature. So when you keep hot things in normal temperature, the heat from hot object transfers to the environment until they are both on the same level. Same happens when a cold object is kept in normal room temperature, the heat from the environment transfers to the cold object until they are both equal. its all about achieving the equilibrium in a system
Answer:
0.0025 sec
Explanation:
Period = 1 / frequency = 1/400 = 0.0025 sec
