A 15.0 cm object is 12.0 cm from a convex mirror that has a focal length of -6.0 cm. What is the height of the image produced by the mirror? A. –5.0 cm B. 7.5 cm C. -7.5 cm D. 5.0 cm
Answer: D. 5cm
Explanation:
Given the following :
Focal length (f) = - 6.0 cm
Height of object = 15.0cm
Distance of object from mirror (u) = 12.0cm
Height of image produced by the mirror =?
Firstly, we calculate the distance of the image from the mirror.
Using the mirror formula
1/f = 1/u + 1/v
1/v = 1/f - 1/u
1/v = 1/-6 - 1/12
1/v = - 1/6 - 1/12
1/v = (- 2 - 1) / 12
1/v = - 3 / 12
v = 12 / - 3
v = - 4
Using the relation :
(Image height / object height) = (- image distance / object distance)
Image height / 15 = - (-4) / 12
Image height / 15 = 4 / 12
Image height = (15 × 4) / 12
Image height = 60 / 12
Image height = 5cm
Answer:
D. 5 cm

HELP WITH THESE TWO PROBS PLEASE
Answer:
1. She is moving at a speed of \(147.18 ms^{-1}\).
2. The speed of the golf ball is \(78.1 m/s\).
Explanation:
1. We can say , at any moment the skydiver is having a kinetic energy of \(1/2 mv^2\)
(where, \(m\) is her mass and \(v\) is the velocity at that point)
Given, \(1/2mv^2 =704000\)
and, \(m = 65KG\)
So, putting the values we get,
\(v=147.18 ms^{-1}\)
2. \(KE=\frac{1}{2} mv^2\)
\(143.3J =\frac{1}{2} (.047)v^2\)
\(v^2=6097.9 m^2/s^2\)
\(v=78.1 m/s\)

Justin and Oscar each hit a baseball with a bat. The baseballs have the same mass, but the ball Justin hits has a greater acceleration. What might be the reason for the greater acceleration of Justin's baseball?
The acceleration is different in both cases because, the force applied is different. Acceleration is force divided by mass of the object. Thus, Justin had greater force than Oscar.
What is force ?Force is an external agent acting on body to change its motion or deform it. There are various kinds of forces such as frictional force, gravitational force, nuclear force etc.
According to Newton's second law of motion, the force acting on an object is the product of its mass and acceleration.
Thus, F = ma
Hence, as the force increases the body is accelerated more.
With the same mass for the two balls, the force used to hit it was different and thus, the acceleration differs in both cases. Therefore, Justin has the greater force.

Use the data in the table to explain how you could determine the volume of the block.
To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.
To find the volume of the block using the measurements provided.
1. Calculate the change in water volume:
The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.
2. Convert the change in water volume to cubic centimeters:
Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.
3. Determine the volume of the block:
When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.
By following these steps, we can find the volume of the block based on the provided measurements.
Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.
