Answer:
(A) As it moves farther and farther from Q, its speed will keep increasing.
Explanation:
When a positive charge Q is fixed on a horizontal frictionless tabletop and a second charge q is released near to it then according to the Coulombs law the force acting on it decreases with the square of the distance between them.
Mathematically:
where:
r = distance between the charges
permittivity of free space
By the Newtons' second law of motion if the we know that the acceleration is directly proportional to the force applied. So as the distance between the charges increases the its acceleration also decreases therefore now the charge feels less acceleration but still continues to accelerate with a fading magnitude.
Limestone, Sandstone, and Shale would be the answer.
Answer:
The height of father = 178 cm.
Explanation:
The height of your father is 70 inches.
There are 2.54 centimeters in an inch
1 inch = 2.54 cm
70 inches = 70 x 2.54 = 177.8 cm
Rounding to the nearest centimeter.
70 inches = 177.8 cm = 178 cm
The height of father = 178 cm.
the second option, Electric into Thermal
