The size of the star defines wither of not it is a dwarf star, or a red giant.
Answer:
Explanation:
It is determined by the amount of cold or hot water in the mixture to know if it will be closer to been hot or cold.
Answer:
To make a change between these two units of measurement, the formula to be used is kg x 9.807 = N which is the same conversion used automatically by the kg to N conversion calculator. As an example, 2kg = 19.6N and 5kg = 49N.
Explana
Answer:
Specific heat at constant pressure is = 1.005 kJ/kg.K
Specific heat at constant volume is = 0.718 kJ/kg.K
Explanation:
given data
temperature T1 = 50°C
temperature T2 = 80°C
solution
we know energy require to heat the air is express as
for constant pressure and volume
Q = m × c × ΔT ........................1
here m is mass of the gas and c is specific heat of the gas and Δ
T is change in temperature of the gas
here both Mass and temperature difference is equal and energy required is dependent on specific heat of air.
and here at constant pressure Specific heat is greater than the specific heat at constant volume,
so the amount of heat required to raise the temperature of one unit mass by one degree at constant pressure is
Specific heat at constant pressure is = 1.005 kJ/kg.K
and
Specific heat at constant volume is = 0.718 kJ/kg.K
Answer:
torque = 3.897 N-m
Explanation:
given data
force = 300 N
angle = 60 degree
distance = 15 cm
to find out
torque
solution
we will apply here torque formula that is given below
torque = force × sinθ × distance ...................1
put here all these value in equation 1
we get torque
torque = force × sinθ × distance
torque = 300 × sin60 × 1.5 ×
torque = 300 × 0.8660 × 1.5 ×
torque = 259.80 × 1.5 ×
torque = 389.711 ×
torque = 3.897 N-m
