Explanation:
In this case we need to say that out of the attached figure which shows that the object is in uniform circular motion.
When and object moves in a circular path, its motion is called circular motion. In this type of motion, the speed of the object remains constant while its position changes i.e. its velocity changes.
Out of attached options, V shows circular motion, as the object is position continuously. W and Y are similar cases.
So, V, X and Y shows the circular motion of the object. Hence, this is the required solution.
suppose the mass of a metal object be m and its specific heat capacity be s, and, H joules of heat is required to raise its temperature by t degrees Celsius
Than H is given by relation,
Now if this object is cut in two half's, than mass of half part will also be half <em>i.e. </em>M/2
So heat required to heat the half part will be
Hence, the heat required to raise the half object to a specific temperature will also become half.
Answer:
The distance traveled by the balloon is 10.77 m
Explanation:
velocity of the ball, = 2 m/s south
velocity of the air, = 5 m/s west
To determine the distance the balloon will travel after 2 seconds, first determine the resultant velocity of the balloon.
| 2m/s
|

↓
5m/s ←------------------
the two velocities forms a right angled triangle and the resultant will be the hypotenuses side of the triangle.
R² = 5² + 2²
R² = 29
R = √29
R = 5.385 m/s
The distance traveled by the balloon is calculated as;
d = R x t
where;
t is time of the motion = 2 seconds
d = 5.385 x 2
d = 10.77 m
Therefore, the distance traveled by the balloon is 10.77 m.
