Answer:
1.0798 × 10^2kg
Explanation:
1 mg = 1 × 10-6 kg therefore we can multiply 10798 by 1 × 10-6 we will get the amount of kg.
10798 × (1 × 10-6) = 1.0798 × 10^2kg
Answer: A) Andaman Island Explanation: India’s only active volcano is located at the Andaman and Nicobar Islands.
Answer:
Mass of water = 41.8 g
Explanation:
Given data:
Mass of water = ?
Change in temperature = 3.0 °C
Specific heat capacity = 4.184 j/g.°C
Heat absorbed = 525 j
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 3.0°C
Now we will put the values in formula.
525 J = m × 4.184 j/g.°C × 3.0°C
525 J = m × 12.552 j/g
m = 525 J/ 12.552 j/g
m = 41.8 g
Answer:
E. Fracking
Explanation:
The process involves the high-pressure injection of 'fracking fluid' into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely.
