James (mass 95.0 kg ) and Ramon (mass 67.0 kg ) are 20.0 m apart on a frozen pond. Midway between them is a mug of their favorit
SOVA2 [1]

Answer:

The speed of James is 0.776 m/s

Explanation:

Step 1: Data given

mass of James = 95.0 kg

mass of Ramon = 67.0 kg

We consider James and Ramon and the rope to a single system. This means that the net external forces on the system = 0

.The momentum = 0, so the sum of the momentum of each part must be 0 in total.

Step 2: Calculate the speed of James

m(james) *v(James) = m(Ramon) * v(Ramon)

with m(James) = the mass of James = 95.0 kg

with v(James) = speed of James = TO BE DETERMINED

with m(Ramon) = mass of Ramon = 67.0 kg

with v(Ramon) = speed of Ramon = 1.10 m/s

v(James) =  (m(Ramon) * v(Ramon))/ m(james)

v(James) = (67.0 kg* 1.10 m/s) / 95.0 kg

v(James) = 0.776 m/s

The speed of James is 0.776 m/s

A spring has been compressed inside a toy what kind of energy is this
zlopas [31]

Answer:

Elastic Potential Energy

Explanation:

Elastic Potential Energy (“Spring Energy”) is the form of energy an object has when it is stretched, compressed, twisted, bent, or otherwise has its shape changed as long as the object resists and will try to return to its original state.

The magnetic field at the equator points north. If you throw a positively charged object (for example, a baseball with some elec
PilotLPTM [1.2K]

Answer:

The magnetic force points in the positive z-direction, which corresponds to the upward direction.

Option 2 is correct, the force points in the upwards direction.

Explanation:

The magnetic force on any charge is given as the cross product of qv and B

F = qv × B

where q = charge on the ball thrown = +q (Since it is positively charged)

v = velocity of the charged ball = (+vî) (velocity is in the eastern direction)

B = Magnetic field = (+Bj) (Magnetic field is in the northern direction; pointing forward)

F = qv × B = (+qvî) × (Bj)

F =

| î j k |

| qv 0 0|

| 0 B 0

F = i(0 - 0) - j(0 - 0) + k(qvB - 0)

F = (qvB)k N

The force is in the z-direction.

We could also use the right hand rule; if we point the index finger east (direction of the velocity), the middle finger northwards (direction of the magnetic field), the thumb points in the upward direction (direction of the magnetic force). Hence, the magnetic force is acting upwards, in the positive z-direction too.

Hope this Helps!!!
