Watt is a unit for power that is also equal to J/s. We therefore need to convert the minutes to seconds first before answering. Every minute is comprised of 60 seconds. Therefore, 3 minutes are composed of 180 seconds. Multiplying the number of seconds to the given power will give us,
Work = Power x time
= (1500 J/s) x (180 s)
= 270,000 J
Therefore, the answer is letter D.

insens350 [35]

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.

What is the definition of the half-life of a radioactive isotope?

kolbaska11 [484]

Answer: The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. In 14 more days, half of that remaining half will decay, and so on.
