Thermal energy quantifies the amount of heat present in the body and is calculated through the equation,
H = mcpdT
where H is the heat, m is the mass, cp is the specific heat, and dT is the temperature difference. If all things are constant, and the thermal energy is halved then, dT should also be reduced to half.
The statement: "<span>A change in the thermal energy of an object is related to the object s specific heat, temperature change, and mass.</span>" is True. An object's total heat capacity is called heat capacity, and it is affected by the amount of thermal energy required to raise the temperature by 1 degree C.
The spring constant is computed by:
F = kx
Where: F is the force applied in newtons (N)
k is the spring constant measured in newtons per meter (N/m); and
x is the distance the spring is stretched (m)
and
F = mg
Where: F is the force pulling objects in the direction of the Earth.
m is the mass of the object.
g is the acceleration due to gravity;
So plugging our values in the formula:
F = mg
= (1.8) (9.81) = 17.658N
k =
F/x = 17.658 /0.09 = 196.2 N/meter
Answer:
There would be a pressure drop in the direction of the higher opening. This will force air to move in from the lower opening and force it to leave through the higher opening. This will create a convectional movement of air, cooling and ventilating the tunnel.
Explanation:
This is in accordance with bernoulli's law of fluid flow which states that the pressure exerted by a moving fluid is lesser than it would exert if it were at rest.
Answer:
It is wrong to say that "a single object all alone is moving" simply because it goes against Newton's law of inertia.
Explanation:
From Newton's law of inertia, it states that: An object at rest or in constant motion will continue in it's present state unless it is acted upon by an external force.
Which means that a single object by itself cannot move anywhere unless it is acted upon by an external force..
Thus, it is wrong to say that "a single object all alone is moving" simply because it goes against Newton's law of inertia.
