Answer:
(a) The length of the pendulum on Earth is 36.8cm
(b) The length of the pendulum on Mars is 13.5cm
(c) Mass suspended from the spring on Earth is 0.37kg
(d) Mass suspended from the spring on Mars is 0.36kg
Explanation:
Period = 1.2s, free fall acceleration on Earth = 9.8m/s^2, free fall acceleration on Mars = 3.7m/s^2
( a) Length of pendulum on Earth = [( period ÷ 2π)^2] × acceleration = (1.2 ÷ 2×3.142)^2 × 9.8 = 0.0365×9.8 = 0.358m = 35.8cm
(b) Length of the pendulum on Mars = (1.2÷2×3.142)^2 × 3.7 = 0.0365×3.7 = 0.135cm = 13.5m
(c) Mass suspended from the spring on Earth = (force constant×length in meter) ÷ acceleration = (10×0.358) ÷ 9.8 = 0.37kg
(d) Mass suspended from the spring on Mars = (10×0.135)÷3.7 = 0.36kg
Answer:
The chemical energy of the battery was reduced in 10800J
Explanation:
The first thing to take into account is that the stored energy in a battery is in Watts per second or Joules (
). It means that the battery provides a power for a certain time.
The idea is to know how much
has been consumed by the circuit.
The first step is to know the power that is consumed by the circuit. It is
. The problem says that the circuit consumes a current of 5.0A with a voltage of 6.0V. It means that the power consumed is:

The previous value (30W) is the power that the circuit consumes.
Now, you must find the total amount of power that is consumed by the circuit in 6.0 minutes. You just have to multiply the power that the circuit consumed by the time it worked, it means, 6.0 minutes.

You must convert the minutes unit to seconds. Remember that 1 minute has 60 seconds.

Thus, the chemical energy of the battery was reduced in 10800J
Answer:
option A
Explanation:
The meteor shower is the celestial activity in which meteors are observed to radiate or originate from one point.
Meteors are nothing but dust or ice from the trails of comets. Most of the meteors are less than the size of the sand particle.
We will see comet shower when we earth will cross the orbit of the comet.
Hence, the correct answer is option A
