➷ Use this equation:
Q = IT
Rearrange for I
I = Q/T
Substitute in the values:
I = 240/3
I = 80
The electric current is 80 amps.

Answer:
Explanation:
The centripetal acceleration of the child, which is moving by uniform circular motion, is given by
where
v = 5 m/s is the tangential speed of the child
r = 1.2 m is the radius of the circular path
Substituting the numbers into the equation, we find
Answer:
20 m/s
Explanation:
The vertical component of the velocity of the ball is equal to the length of the perpendicular of a triangle such that it makes an angle of 30 degrees from the base and the length of the hypotenuse is 40 m/s. Sin(∅)*hypotenuse is the length of the perpendicular.
Vertical component of velocity is given by 40Sin(30°)=20
Answer:

Answer:
About 175 million years ago.
Explanation:
Approximately 335 million years ago , the scattered landforms on the earth surface assembled to form super-continents also called Pangea . It existed during late Paleozoic and Mesojoic era .It again started breaking away about 175 million years ago to form the present continents. Much of the Pangea was in the southern hemisphere surrounded by super-ocean.
