Answer:
The length and the magnification of this telescope are 41 cm and 0.108.
Explanation:
Given that,
Focal length of first lens f= 4.0 cm
Focal length of other lens f'= 37 cm
We need to calculate the length of the telescope
Using formula of length
Put the value into the formula
We need to calculate the magnification of the telescope
Using formula of the magnification
Put the value into the formula
Hence, The length and the magnification of this telescope are 41 cm and 0.108.
The conclusions that are specifically supported by the data in Table 1 is that An increase in the number of rubber bands causes an increase in the acceleration. That is option D.
<h3>What is acceleration?</h3>Acceleration is defined as the rate at which the velocity of a moving object changes with respect to time which is measured in meter per second per second (m/s²).
From the table given,
Trial 1 ----> 1 band = 0.24m/s²
Trial 2 ----> 2 bands = 0.51 m/s²
Trial 3 ----> 3 bands = 0.73 m/s²
Trial 4 -----> 4 bands = 1.00 m/s²
This clearly shows that increase in the number of bands increases the acceleration of one brick that was placed on the cart.
This is because increasing the number of rubber bands has the effect of doubling the force leading to an effective increase in velocity of the moving cart.
