Students in a Physics class are conducting experiment to know how to increase the strength of an electro magnet. (9b) Student 1- Place another nail with the first and reduce the number of coils
Student 2- use a wooden splint instead of nail and add few more coils around the splint.
Student 3- Remove the nail and connect both ends of the coil to the same battery terminal.
Student 4- add additional wraps around the nail and add another battery to increase the current through the wire. Which student described the steps correctly?

2b2t

explanation:

2b2t

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

note: to earn full marks when solving science word problems, you must show your work:

formula.

example:

given values:

mass = 0.3 kg.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
