Answer:
The size of the image is 1.04 m.
Explanation:
Given that,
Height of object = 2.40 m
Distance of object = 2.60 m
Radius of curvature =4.00 m
Focal length
We need to calculate the image distance
Using mirror formula
We need to calculate the height of the image
Using formula of magnification
Put the value into the formula
Hence, The size of the image is 1.04 m
Answer:
<em><u>energy</u></em>
Explanation:
The heating and cooling of molecule will make <em><u>energy</u></em> change their state of matter.
Answer:
D. 9 N
Explanation:
The tension on the string is equivalent to the centripetal force.
Centripetal force is the force exerted by an object in circular motion or path towards the center of the circular path.
Centripetal force = mv²/r
where m is the mass of the object, v is the velocity and r is the radius of the circular path.
Centripetal force = (0.25 kg × 6²)/ 1
= 9 N
Thus, the tension on the string is 9 N
