Lucas left a metal bowl and a wooden bowl outside overnight. The next morning, he picked up the bowls to bring them inside. He n

oticed that the metal bowl felt much cooler than the wooden bowl. His father explained that both bowls were actually the same temperature. Which statement best describes why the metal bowl felt cooler even though the bowls were the same temperature?
A
Wood transfers heat away from the skin by convection, creating the sensation of warmth.

B
Metal removes moisture from the skin by absorption, creating the sensation of coolness.

C
Metal transfers heat away from the skin by conduction, creating the sensation of coolness.

Answer: C. Metal transfers heat away from the skin by conduction, creating the sensation of coolness.

Explanation: The skin releases heat into the metal bowl since there is a difference in temperature between the two objects. So heat is taken away from the hand abd transfers into the metal bowl by conduction creating a cooler sensation.

The time taken for an object to fall from a height of h m from the earth'fs surface is t s.
telo118 [61]

Answer:

B. Longer than t s,

Explanation:

Gravitational accln on earth is 9.8 m/s^2,

and one you provided as on moon is 1.6 m/s^2

that mean on moon gr. accl. is lesser!

now the time taken on earth will be lesser cuz from the same height if you drop the object from rest!

since accln on earth is higher,the object will attain higher velocity as compare to that of on moon!

The quantity of charge through a conductor is modeled as Q = (3.00 mC/s4)t4 − (2.00 mC/s)t + 9.00 mC. What is the current (in A)
Mumz [18]

Answer:

The current at time t = 4.00 s is 0.766 A.

Explanation:

Given that,

The quantity of charge through a conductor is modeled as :

Q=(3t^4-2t+9)\ mC

We need to find the current (in A) at time t = 4.00 s. We know that the rate of change of electric charge is called electric current. It is given by :

I=\dfrac{dQ}{dt}\\\\I=\dfrac{d(3t^4-2t+9)}{dt}\\\\I=12t^3-2

At t = 4 s

I=12(4)^3-2=766\ mC/s\\\\I=0.766\ C/s=0.766\ A

So, the current at time t = 4.00 s is 0.766 A. Hence, this is the required solution.

The sides of a rectangle are 6.01 meters and 12 meters. Taking the significant figures into account, what is the area of the rec
Contact [7]
Taking significant figures into account, 6.01 has 3 significant figures, and 12 meters has 2. In the rule of multiplication, the answer has to follow the least number of significant figures. This means that the answer we obtain must have only 2 significant figures. To find the area of the rectangle, the two sides are merely multiplied. This is shown below:

6.01 * 12 = 72.12 = 72

Therefore, the area is 72 sq. meters
