Answer:
increase the time the force acts or you could increase the number of temptations.
hope this helped!
I’m not really sure but I think it’s D type 1 lever
Answer:
Explanation:
Expression for time period of a pendulum is as follows
T = ![2\pi\sqrt{\frac{l}{g} }](https://tex.z-dn.net/?f=2%5Cpi%5Csqrt%7B%5Cfrac%7Bl%7D%7Bg%7D%20%7D)
l is length of pendulum from centre of bob and g is acceleration due to gravity
Given
Time period T = 1.583
g = 9.846
Substituting the values
1.583 = ![2\pi\sqrt{\frac{l}{9.846} }](https://tex.z-dn.net/?f=2%5Cpi%5Csqrt%7B%5Cfrac%7Bl%7D%7B9.846%7D%20%7D)
l = ![\frac{(1.583)^2\times9.846}{4\times(\frac{22}{7})^2 }](https://tex.z-dn.net/?f=%5Cfrac%7B%281.583%29%5E2%5Ctimes9.846%7D%7B4%5Ctimes%28%5Cfrac%7B22%7D%7B7%7D%29%5E2%20%7D)
l = .6244 m
= 62.44 cm
Length of rod = length of pendulum - radius of bob
= 62.44 - 13.62
= 48.82 cm
= .488 m
Answer:
The theory of plate tectonics describes the movement of the plates across the Earth's lithosphere (the crust and upper mantle) through immense periods of time. Earth's litoshphere is composed of 7 (or 8, depending on how they are defined) major plates and many more minor plates.
The movement is attributed to different phenomena stemming from Earth's rotation, gravity, and mantle dynamics. All of these forces play a role in influencing the size, shape, and positioning of the different landmasses that currently shape our continents and islands.
Explanation:
In a nutshell, land originated from magma in the Earth's core escaping through the cracks and making its way to the ocean. The water cooled down the magma and this process created all of the land both above and below the sea. The landforms that we see all around the Earth today were formed thanks to collisions and separations of the plates thoughout billions of years.
