Distance, since distance represents how far something has travelled, which would be in our case 2.5m.

An object moves 2.5 m. This is an example of a distance

Answer: Option B

<u>Explanation:</u>

In the above example, the direction of the object in which it moved is not given here. Hence Option A is invalid. Velocity and speed are similar as they indicate the distance travelled by the object with respect to time.

The distance travelled by the object with respect to time is not given in the example and so Option C and  D are invalid. So distance is the best option.

Ghella [55]

Answer : B.  0 m/s∧2

Now we know that velocity = distance/ time

And acceleration = velocity/time.


From the graph we see that at the time interval 2 secs,the distance travelled is 10 m. Hence the velocity(v1) =10/2 = 5m/s.

From the graph we see that at the time interval 5 secs,the distance travelled is 25 m. Hence the velocity (v2) =25/5 = 5m/s.

Now acceleceration between the time interval of 2 ad 5 secs is calculated as

(v1-v2)/t2-t1 = (5-5)/(5-2) = 0 m/s∧2

A solid metal sphere of diameter D is spinning in a gravity-free region of space with an angular velocity of ωi. The sphere is s
Leona [35]

Answer:

0.6

Explanation:

The volume of a sphere = \frac{4}{3} \pi (\frac{D}{2})^3

Therefore \pi * r^2 * (\frac{D}{2} ) = \frac{4}{3} \pi (\frac{D}{2})^3

r of the disc = 1.15(\frac{ D}{2} )

Using conservation of angular momentum;

The M_i of the sphere = \frac{2}{5} m \frac{D}{2}^2

M_i of the disc = m*\frac{   \frac{1.15*D}{2}^2 }{2}

\frac{wd}{ws} = \frac{\frac{2}{5}m * \frac{D}{2}^2}{  m * \frac{(\frac{`.`5*D}{2})^2 }{2} }

= 0.6

When throwing a ball upwards, the velocity is positive, and the acceleration is negative. True of False?
Setler79 [48]

Answer:

The velocity & acceleration will be taken as negative when a ball is thrown upward because work is done against the gravity.

What is happening if energy input remains constant and voltage remains the same in a circuit, but the current decreases?
atroni [7]
The resistance of the circuit will definitely increase. This can be proved by the Ohm's Law where it is said that the potential difference across a conductor is directly proportional to the current and the proportionality constant is known as the resistance. The law is expressed as V = IR. As we can see, when the voltage remains constant while the current decreases then the resistance will increase.<span />
