Answer:
K=24.17 x 10⁻² J s⁻¹c⁻¹m⁻¹
Explanation:
Rate of flow of heat through a material is given by the following expression
where Q is amount of heat flowing in time t through area A and a medium of thickness d having two faces at temperature difference δT . K is thermal conductivity of the medium .
Here Q = 3.34 x 10⁶/6 , t = 24 x 60 x 60 = 86400 s , A = .332 X .332 = .0110224 m² , δT = 104.7
Put these values here
K=24.17 x 10⁻² J s⁻¹c⁻¹m⁻¹
Due to the principle of conservation of energy, the work done by the engine to move the scooter converts into kinetic energy of the scooter:
where M is the combined mass of scooter and rider, and v is the velocity of the scooter. Therefore, we can find the velocity as:
where M is the combined mass of scooter and rider, and v is the velocity of the scooter. Therefore, we can find the velocity as:
Answer:
48.4293354946 N
Yes
Explanation:
d = Diameter of rod = 2.95 cm
h = Length of rod = 92.6 cm
= Density of rod = 7800 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Volume of rod
Mass is given by
Weight is given by
The weight of the rod is 48.4293354946 N
The mass of the rod is 4.93673144695 kg which is light. So, I will be able to carry the rod without a cart.
