The temperature of a 2.0kg block increases by 5C when 2000 J of thermal energy are added to the block. What is the specific heat

of the block
Physics

Explanation:

Q=mc(T2-T1)

or

q = mcΔT ,

where m is the mass of the sample,

c is the specific heat,

and ΔT is the temperature change.

Q=2.0 × 2000 × 5

Q=20000J⋅kg −1 ⋅K −1

What has more thermal energy? A giant, frozen iceberg or a swimming pool filled with boiling water? Explain.​
padilas [110]

Boiling water has a lot more heat than the oven's air (even though the air has a higher temperature). ... A match has a greater temperature than the iceberg because the average molecule in the match is moving faster than the average molecule in the iceberg

A pilot heads her jet due east. The jet has a speed of 425 mi/h relative to the air (in other words, if the air were still, the
Elza [17]

Answer:

The resultant velocity of the jet as a vector in component form 426.87 mi/hr 5.36 degrees North.

Explanation:

Vectors are quantities that have their magnitude and direction .

Sketching out the problem given, by using straight lines to represent each of the vectors, we will have a right angled triangle as shown below.

The solution can be obtained by applying Pythagoras theorem to

resolve the vectors.

Velocity of jet plane = 425 mi/hr

velocity of air = 40 mi/hr

Resultant of the vectors =\sqrt[]{425^{2}+40^{2}}=426.87 mi/hr

Vector direction =tan^{-1}(\frac{40}{425})= 5.36 degrees

hence the velocity is 426.87 mi/hr in a direction 5.36 degrees inclined Northward
