Answer: hello your question is incomplete below is the missing part

A spherical cavity is hollowed out of the interior of a neutral conducting sphere. At the center of the cavity is a point charge, of positive charge q.

answer:

- q

Explanation:

Since the spherical cavity was carved out of a neutral conducting sphere hence the electric field inside this conductor = zero

given that there is a point charge +q at the center of the spherical cavity hence for the electric field inside the conductor to be = zero the total surface charge qint on the wall of the cavity will be -q

A horizontal rope is tied to a 57.0 kg kg box on frictionless ice. What is the tension in the rope if: You may want to review (P
VARVARA [1.3K]

Answer:

Explanation:

A ) The surface is frictionless . If the box is at rest , there will be no tension in the rope.

B ) In this case , the box is moving with steady rate of 4.20 m /s . In this case also no force is acting on the box so tension in the rope will be nil.

C ) In this case the box is moving with acceleration of 5.8 m /s² so force on the box = mass x acceleration

= 57 x 5.8

= 330.6 N .

So tension in the rope will be equal to force acting on the rope . Hence tension = 330.6 N .

The frequency of a wavelength ?
serious [3.7K]

Answer:

f=0.1

Explanation:

Use the equation:

f=\frac{1}{T} (where T is the period)

f=\frac{1}{9} (9 comes from the period of a full wavelength)

f=0.1

An object moves 12 m to the right. If its acceleration was 2 m/s and its final velocity is 25 m/s, find its initial velocity.
scoundrel [369]

Explanation:

by the formula, v²-u²=2aS

S=12m, a=2m/s², v=25m/s, u=?

v²-u²=2aS

25²-u²=2×2×12

-u²=48-625

-u²=-577

u²=577

u=√577

u = 24.02m/s

hope this helps you.

Can classical physics be used to accurately describe a satellite moving at a speed of 7500 m/s? explain why or why not.
gogolik [260]

The classical physics works on the Newton's laws of motion. It is applicable on heavenly bodies which are governed by the gravitational force. On the other hand, Quantum Physics is applicable for very low mass and sized bodies like electron, protons etc. The classical physics would accurately describe the motion of satellite moving with speed 7500 m/s using the following formula:

r=\frac {GM}{v^{2}}

where G is the gravitational constant, M is the mass of the planet and v is the orbital speed. Then radius of the orbit can be described by this formula.
