Answer:
16.6 kJ/°C
Explanation:
given,
Amount of heat absorbed = 45 kJ
initial temperature, T₁ = 25.5°C
final temperature, T₂ = 28.2°C
change in temperature = T₂ - T₁
= 28.2 - 25.5 = 2.7° C
Heat capacity of the object is equal to 16.6 kJ/°C
The answer is 1 m/s. :::))))
Answer:
-total mass
-location of the axis of rotation
Explanation:
The moment of inertia () is a measure of the rotational inertia (resistance to the change of state of motion) of a body.
This amount depends on the mass distribution of the body and the chosen axis, which is why it must be specified with respect to an axis of rotation.
For example, for the known case of a point mass, its moment of inertia is given by:
Where is the mass and is the distance to the axis of rotation.
Therefore, the moment of inertia of an object depends on its total mass and location of the axis of rotation.
Answer:
θ =28.07⁰
Explanation:
when van moves around an unbanked curve, horizontal component of normal force is equal to centripetal force
---(1)
There is no motion in vertical direction, so vertical component of normal force is balanced with weight of block i.e.
----(2)
divide (1) and (2)
v = 28 m/s
r = 150 m
g = 9.8m/
θ = 28.07⁰
The answer is "Cold Front".
A cold front is characterized as the change zone where a cool air mass is supplanting a hotter air mass. Cold fronts for the most part move from northwest to southeast. The air behind a cold front is recognizably colder and drier than the air in front of it.
