Answer: Radiation
Explanation:
The heat transfer process that is important in the transfer of energy from the Sun to Earth is Radiation.
Radiation is one of the mode of heat transfer which transfer energy/heat from one medium to another without any intervening medium. For example, heat from the sun reaches the earth through radiation. The sun hits the earth directly without any medium between the sun itself and the earth.
<span>the formula q = 375 g * 25 C * 4.186 J / (g*C) = 39,243.75 J q represents the heat in Joules , m the mass in grams, difference of temperature in Celsius degree, and 4.186 J/(g*C) is the specific heat of water( I assume the water is in liquid from and will remain liquid). Approximately 39.24 kJ once you round and transform to kJ..1 kJ=1000J</span>
Answer:
9.801 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 39 ft/s
s = Displacement = 720 cm = 7.2 m
a = Acceleration
Converting to m/s
Equation of motion
Acceleration of the ball is 9.801 m/s²
<span>An endothermic reaction takes heat from it's environment. When you increase the temperature of the environment in which the endothermic reaction is taking place, the forward reaction will be favored and more products will form. The answer is B.</span>
Answer:
Force between two charges is given as 143.3 N
Explanation:
As we know that electrostatic force between two point charges is given as
here we know that
also we know that
so we have
so we have
