The sea is getting fuller.Global warming is causing a rise in a sea level.This is partly due to melting ice in Greenland and Antarctica,and partly due to thermal expansion of the water.The rise so far is about nine inches and the rate has increased to about one inch every seven years.

Answer:

The sea is getting fuller. you just cant see it because it rises by small amounts a time. Global warming is causing a rise in sea level. This is partly due to melting of ice in Greenland and Antarctica, and partly due to thermal expansion of the water. The rise so far is about nine inches and the rate has increased to about one inch every seven years.

luda_lava [24]

Answer:

c. 4.582\times10^{21} kg

Explanation:

r_{i} = Initial distance between asteroid and rock = 7514 km = 7514000 m

r_{f} = Final distance between asteroid and rock = 2823 km = 2823000 m

v_{i} = Initial speed of rock = 136 ms⁻¹

v_{f} = Final speed of rock = 392 ms⁻¹

m = mass of the rock

M = mass of the asteroid

Using conservation of energy

Initial Kinetic energy of rock + Initial gravitational potential energy = Final Kinetic energy of rock + Final gravitational potential energy

(0.5) m v_{i}^{2} - \frac{GMm}{r_{i}} = (0.5) m v_{f}^{2} - \frac{GMm}{r_{f}} \\(0.5) v_{i}^{2} - \frac{GM}{r_{i}} = (0.5) v_{f}^{2} - \frac{GM}{r_{f}} \\(0.5) (136)^{2} - \frac{(6.67\times10^{-11}) M}{(7514000)} = (0.5) (392)^{2} - \frac{(6.67\times10^{-11}) M}{(2823000)} \\M = 4.582\times10^{21} kg

What type of material is good at transferring heat?
MatroZZZ [7]
The answer is A

Materials that are good conductors of thermal energy are called thermal conductors. Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators

What are the parts of a wedge and their function?​
Svet_ta [14]

Answer:

A wedge is a machine that consists of two inclined planes, giving it a thin end and thick end. A wedge is used to cut or split apart objects. Force is applied to the thick end of the wedge, and the wedge applies force to the object along both of its sloping sides. This force causes the object to split apart

Un casquillo de cobre de 8 kilogramos tiene que calentarse de 25 a 140 grados Celsius con el fin de expandirlo pata que se ajust
uranmaximum [27]

Answer:

354200J

Explanation:

Given parameters:

Mass of copper bushing = 8kg

Initial temperature  = 25°C

Final temperature  = 140°C

Unknown:

Quantity of heat required to heat this mass = ?

Solution:

The amount of heat required to heat mass from one temperature to another is given by;

                  H = m c Δt

where m is the mass

          c  is the specific heat

        Δt is the change in temperature

C is a constant and for copper, its value is 385J/kg°C

 Input the parameters;

            H = 8 x 385 x (140 - 25) = 354200J
