Consider the same 70kg/686N student on the surface on another planet from the table above: Jupiter. Tompared to the gravitationa

l force or weight on Earth. How would we expect the student's weight to change? Explain. A) Because the mass of Jupiter is about 300 times greater than Earth's we would expect the student's weight to be 205,800N. B) Both the mass and the diameter of Jupiter is greater than Earth's. Considering both, the student's Earth weight would be multiplied by 3, or 2058N. Because Jupiter is considered a gas giant, rather than a rocky solid planet, there is no gravity and we could not calculate the student's new weight. D) Because the distance to Jupiter is about 500 million km farther from the Sun than Earth, we can expect the weight of the student to be 686N/5 or 137.2N​

N=m*g=7.5*9.81=73.58N 

which is 73.58-23=50.58N less 

so, there the person must pull at 23 degree upward

A dielectric material such as paper is inserted between the plates of a capacitor as the capacitor holds a fixed charge on its p
Vikki [24]

Answer:

Introducing a dielectric into a capacitor decreases the electric field, which decreases the voltage, which increases the capacitance.

Explanation:

A dielectric (or dielectric material) is an electrical insulator that can be polarized by an applied electric field. When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor but only slightly shift from their average equilibrium positions causing dielectric polarization

An insulating cup contains 200 grams of water at 25 ∘C. Some ice cubes at 0 ∘C is placed in the water. The system comes to equil
Nataly [62]

Answer:

The amount of ice added in gram is 32.77g

Explanation:

This problem bothers on the heat capacity of materials

Given data

Mass of water Mw= 200g

Temperature of water θw= 25°c

Temperature of ice θice= 0°c

Equilibrium Temperature θe= 12°c

Mass of ice Mi=???

The specific heat of ice Ci= 2090 J/(kg ∘C)

specific heat of water Cw = 4186 J/(kg ∘C)

latent heat of the ice to water transition Li= 3.33 x10^5 J/kg

heat heat loss by water = heat gained by ice

N/B let us understand something, heat gained by ice is in two phases

Heat require to melt ice at 0°C to water at 0°C

And the heat required to take water from 0°C to equilibrium temperature

Hence

MwCwΔθ=MiLi +MiCiΔθ

Substituting our data we have

200*4186*(25-12)=Mi*3.3x10^5+

Mi*2090(12-0)

837200*13=Mi*3.3x10^5+Mi*2090

10883600=332090Mi

Mi=10883600/332090

Mi= 32.77g
