Answer:
0º - 23.5º - 45º - 90º
Explanation:
The inclination angle of the Earth's axis with respect to its orbit around the Sun, determines that the duration enters the day and the night is different.
If it is not inclined (angle 0º) the two and niches have the same hardness
If the angle were very high (about 90º) the night would be very long, about half of the orbit period about six months.
Based on this presentation we can answer the question
The Sumo exposition from highest to lowest is
0º - 23.5º - 45º - 90º
Answer:
The diameter of the hole increases
Explanation:
Metals expand and contract with temperature. Whenever metal is heated, it usually expands in relation to its thermal expansivity. This expansion leads to a slight increase in surface area.
Once the surface area of the metal changes, this means that the dimensions of the whole metal surface changed. As a result, the diameter of the hole drilled in the metal plate will change also. In our case, the diameter of the hole will increase.
Answer:
Inertia resists change in motion. Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force.
EXAMPLE: when you shake a branch the leaves get detached.
Explanation:
Answer:
(a) 
(b) 
Explanation:
Given:
- Limiting tension of snapping of the rope, T= 387 N
- Weight of the object to be lifted,
- ∴mass,
- height of letting down the weight, h = 6.1 m
(a)
Now,
The force to be compensated for being on the verge of snapping:
(T-w) = 62 N
Therefore, we need to produce and acceleration equivalent to the above force.
∵
(b)
From the equation of motion ,we have:
....................(2)
where:
u= initial velocity= 0 (here, starting from rest)
v= final velocity = ?
s= displacement =h =6.1 m
Now, putting the values in eq. (2)
is the velocity with which the body will hit the ground in the given conditions.
