Answer:
43.868 J
Explanation:
Kinetic energy of a body is the amount of energy possessed by a moving body. The SI unit of kinetic energy is the joule (kg⋅m²⋅s⁻²).
According to classical mechanics, kinetic energy = 1/2 m·v²
Where, m= mass in kg and v= velocity in m/s
Given: m = 19.2 lb and v = 7.10 miles/h
Since, 1 lb= 0.453592 kg
∴ m = 19.2 lb = 19.2 × 0.453592 kg = 8.709 kg
Also, 1 mi = 1609.34 m and 1 h = 3600 sec
∴ v = 7.10 mi/h = 7.10 × 1609.34 m ÷ 3600 sec = 3.174 m/sec
Therefore, <u>kinetic energy of the goose</u> = 1/2 m·v² = 1/2 × (8.709 kg)× (3.174 m/sec)² = 43.868 J
Answer:
They both are describing the same thing which is the state of atmosphere.
Explanation:
They are not really the same since weather is what you experience everyday and Climate is the weather over a long period of time.
Answer:
2.3 g NaCl
Explanation:
Given the concentration of the NaCl solution = 0.92% (w/v)
It means that 0.92 g of NaCl is present in 100 mL of water.
Thus,
100 mL of water contains 0.92 g of NaCl
To find, amount of NaCl in 250 mL of water
So,
1 mL of water contains of NaCl
250 mL of water contains of NaCl
<u>2.3 g of NaCl is present in 250 mL of this solution.</u>
Mexico, because it is closer to the equator and it has more deserts, as Canada is known for being cold and snowy.
Answer:
The sun uses nuclear fusion reactions to generate heat.
Explanation:
It is true from the given choices that the sun uses nuclear fusion reactions to generate heat.
The heat that accompanies nuclear fusion reactions is very huge. In fact this is the source of energy for the whole solar system.
During a nuclear fusion reaction, small atomic nuclei combines to form larger ones.
This combination results in a series of chain reactions that releases energy.
