A 92-kg receiver running at 8 m/s catches a pass across the middle and is immediately brought to a stop during a collision with
sammy [17]

Answer: 1200\ N

Explanation:

Given

Mass of receiver m=92\ kg

Running at a speed of v=8\ m/s

time taken to stop t=0.6\ s

We know, impulse imparted is given by

\Rightarrow F\cdot dt=m\Delta v\\\Rightarrow F(0.6)=90(8-0)\\\\\Rightarrow F=\dfrac{90\times 8}{0.6}\\\\\Rightarrow F=1200\ N

Thus, 1200 N is needed to stop the receiver.

The saturnian moon io probably collided with
LUCKY_DIMON [66]
The Voyager and Pioneer flybys of the 1970s and 1980s provided rough sketches of Saturn’s moons. But during its many years in Saturn orbit, Cassini discovered previously unknown moons, solved mysteries about known ones, studied their interactions with the rings and revealed how sharply different the moons are from one another.

Consider a particle with unit charge q, and mass m, in a constant magnetic field B directed along the positive z–axis. The parti
max2010maxim [7]

Answer:

it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.

Explanation:

Magnetic field is along z axis while velocity is in x-z plane

so we will have

F = q(\vec v \times \vec B)

so here we can say

F = q(u\hat i + w\hat k) \times (B \hat k)

so we will have

F = quB(-\hat j)

so here the net force on the charge is perpendicular to its x directional velocity along - Y direction

So due to this component of motion it will move along a circle while other component of the motion will remain uniform always

So here it is combination of two parts

1) Uniform circular motion

2) Uniform motion

So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.

HELPPP WILL GIVE BRAINLIEST!!!!
marishachu [46]

Explanation:

Thermal energy is basically the energy derived from heat when there is a temperature change in a body.

Kinetic energy is the energy due to the motion of a body.

Potential energy is the energy at rest or due to the position of a body.

  • Thermal energy is highly related to kinetic and potential energy.
  • Thermal energy is a type of kinetic energy because it causes the motion of the particles in a body.
  • An increase in thermal energy gives the particles more energy to move and then, their kinetic energy increases.
  • Kinetic energy is directly related to thermal energy.
  • A low thermal energy increases the potential energy in a body.
  • A body at rest will exert its maximum potential energy.
