Answer:

Explanation:

lthough the earliest examples of mummification were accidental, with bodies being preserved because of very dry, desert conditions, it soon became religiously important in ancient Egypt and was done deliberately. Ancient Egyptians believed that a happy afterlife depended in part on careful mummification. The word mummification is formed with the suffix -fication, "a making or causing," and mummy, from the Arabic mumiyah, "embalmed body," from the Persian root mum, "wax."

Two hockey players have a total momentum of +200 kg x m/s before a collision (+ is to the right). After the collision, they move

Juliette [100K]

Total momentum after the collision: +200 kg m/s to the right

Explanation:

We can answer this question by using the law of conservation of momentum, which states that for an isolated system (=no external forces acting on the system), the total momentum is conserved.

Mathematically,

$p_i=p_f$

where

$p_i$ is the total momentum before the collision

$p_f$ is the total momentum after the collision

In this problem, the system consists of two hockey players. Before the collision, their total momentum is

$p_i = +200 kg m/s$ (to the right)

Therefore, according to the law of conservation of momentum, their total momentum after the collision must be the same:

$p_f = +200 kg m/s$

And given that the sign is +, the direction is still the same, therefore to the right.

A steel ball and a piece of clay have equal mass. They are dropped from the same height on a horizontal steel platform. The ball

emmasim [6.3K]

Answer: The ball (option A)

Explanation: change in momentum is defined by the formulae m(v - u) where m = mass of object, v = final velocity and u = initial velocity.

For the ball, it hits the ground and bounces back with the same speed, that's final velocity equals initials (v = - u)

Change in momentum = m( -u- u) = m(-2u) = m(-2u) = -2mu

For the clay, it final velocity is zero since it sticks to the floor, hence (v =0)

m(v - u) = m(0 - u) = - mu.

-2mu (change in momentum from the ball) is greater than - mu ( change in momentum of clay)

A coil of area 0.320 m2 is rotating at 100 rev/s with the axis of rotation perpendicular to a 0.430 T magnetic field. If the coi

weqwewe [10]

Answer:

The maximum emf generated in the coil is 60527.49 V

Explanation:

Given;

area of coil, A = 0.320 m²

angular frequency, f = 100 rev/s

magnetic field, B = 0.43 T

number of turns, N = 700 turns

The maximum emf generated in the coil is calculated as,

E = NBAω

where;

ω is the angular speed = 2πf

E = NBA(2πf)

Substitute in the given values and solve for E

E = 700 x 0.43 x 0.32 x 2π x 100

E = 60527.49 V

Therefore, the maximum emf generated in the coil is 60527.49 V
