Explanation:
Given that,
Mass of the shopping cart, 
Initial speed of the shopping cart, 
Mass of the box, 
Initial speed of the box, 
(at rest)
They stick together and continue moving at a new velocity. It is a case of inelastic collision.
(a) The momentum of the shopping cart before the collision is given by :
(b) The momentum of the box before the collision is given by :
(c) The velocity of the combined shopping cart/box wreckage after the collision is given by using the conservation of momentum as :
Hence, this is the required solution.
4. Dark Energy.
This is the mysterious force causing the expansion of space. No one has ever seen this force.
Answer:
Q = 836.4 Joules.
Explanation:
Given the following data;
Mass = 100 grams
Initial temperature = 25°C
Final temperature = 45°C
We know that the specific heat capacity of water is equal to 4.182 J/g°C.
To find the quantity of heat;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 45 - 25
dt = 20°C
Substituting the values into the equation, we have;
Q = 836.4 Joules.
