Answer:
Thermogenesis:Your body's muscles, organs, and brain produce heat in a variety of ways
Explanation:
For example, muscles can produce heat by shivering. Hormonal thermogenesis: Your thyroid gland releases hormones to increase your metabolism. This increases the energy your body creates and the amount of heat it produces
Answer:
7.45
Explanation:
At 3.0 m PE = m*g*3.0, KE = m*g*(4.0 - 3.0)
At 2.0 m PE = m*g*2.0, KE = m*g*(4.0 - 2.0)
At 3.0 m PE = m*g*1.0, KE = m*g*(4.0 - 1.0)
At 0 m PE = 0, KE = m*g*h = total energy = 7.45 J
The change in momentum of an object equals the impulse applied to it
Answer:
Frequency change by a factor of 2.
(b) is correct option.
Explanation:
Given that,
Mass = 16 kg
Replaced mass = 4 kg
We need to calculate the frequency
Using formula of frequency
Put the value into the formula
....(I)
...(II)
Hence, Frequency change by a factor of 2.
Answer:
A) 2.5 * 10^22 molecules
B) 3.33 * 10^-9 m
C) 1134 miles/hour
D) average spacing = 2.1 m , New mass = 17 kg
Explanation:
Given data :
diameter of atom = 10^-10 m
volume of air = 1 liter
molar masses : 28 g/mol of N2, 32 g/mol of O2
atmospheric pressure = 10^5 Pa
attached below is the detailed solution
