Answer:
Weight = 98 kg.m/s^2
= 98 N.
Explanation:
Weight of an object is defined as the product of mass of the object and the acceleration due to gravity acting on the object. Its unit is Newton which is denoted as N and is also equivalent to kg.m/s^2.
Mass of the object = 10 kg
Acceleration due to gravity, g = 9.8 m/s^2
Weight = m*g
= 10 kg * 9.8 m/s^2
= 98 kg.m/s^2
= 98 N
Answer:Sunlight travels through space without the aid of fluids or solids
Explanation: Radiation involves transfer of energy or heat with the help of electromagnetic waves.
For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.
