Answer:

A) a low specific heat.

Explanation:

As we know that heat given to the sand will increase it temperature

so we can say

Q = ms\Delta T

here we will have

\Delta T = \frac{Q}{ms}

so now we will have

more change in temperature due to heat given to the sand will show that it must have low specific heat capacity as it inversely depends on the specific heat capacity of the sand

so correct answer will be

A) a low specific heat.

SSSSS [86.1K]

Answer:

50mph,60mph

Explanation:

Let speed of southbound train=x mph

Speed of northbound train,y=x+16 mph

Distance between two trains after 1.5 hour,174 miles.

We have to find the speed of two trains.

Distance=speed\times time

Using the formula

174=1.5x+1.5(x+16)

174=1.5(x+x+16)

174=(2x+16)\times 1.5

174=3x+24

3x=174-24=150

x=\frac{150}{3}=50mph

y=x+16=50+16=66mph

Does hot water always freeze faster than cold water
svp [43]
Yes because there is more temperature to cover in terms of hot water turning into cold and then solid water, and therefore hot water cools down faster, whereas cold water will take more time to become solid.

Change in v= 9.8 m/s2xt. The diagram shows a ball falling toward Earth in<br> a vacuum.
Tresset [83]

Answer:

Option A. 39.2 m/s

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 0 m/s

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) = 4 s

Final velocity (v) =?

v = u + gt

Since the initial velocity (u) is 0, the above equation becomes:

v = gt

Thus, inputting the value of g and t, we can obtain the value of v as shown below:

v = 9.8 × 4

v = 39.2 m/s

Therefore, the velocity of the ball at 4 s is 39.2 m/s.
