Answer:
a= 1.81 m/s²
Explanation:
Ratio of the weights on both surfaces can be calculated as,
=
Here;
Wa is the weight on the asteroid, 
is weight on earth,
m is mass of pack, a is acceleration due to an asteroid and
g is acceleration due to gravity.
Rearrange above equation for a,
a=g (
)
Substitute 3.24 N for Wa, 17.5 N for ,
9.81 m/s² for g in the above equation,
a= 9.81(
)
a= 1.81 m/s²
Answer:
As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. ... Thus, entropy measurement is a way of distinguishing the past from the future.

Answer:
Explanation:
Option C is the correct answer
X ray is one of the electromagnetic waves.
As per Clark Maxwell's electromagnetic theory, all the electromagnetic waves move with the velocity of light i.e c= 3×10^8 m/s
In case of electromagnetic waves,the electric field and magnetic field are perpendicular to each other as well as perpendicular to the direction of propagation.The electromagnetic waves exhibit the property of polarisation. Hence they are transverse in nature.
Hence the best statements about X- ray will be-
1- X -rays are electromagnetic waves
2-X-rays are transverse transverse waves
3- X- rays travel at the speed of light.
