<span>Conduction is the process of freezing outside on a cold day. Conduction is usually the process of transfer of heat that is temperature from one body to another body which the difference in their heat energy. This transfer of energy which makes it freeze is also considered as conduction.</span>
Answer:
The minimum total speed is 11.2km/s
Explanation:
We are been asked to find the escape velocity.
Escape velocity is defined as the minimum initial velocity that will take a body(projectile)away above the surface of a planet(earth) when it's projected vertically upwards.
The formula to calculate the escape velocity is Ve = √2gR
For the earth g = 9.8m/s2 , R = 6.4*10^6
Substituting into the equation Ve = √2*9.8*6.4*10^6 = 11.2*10^3m/s
=11.2km/s
I believe it is B, the object that reflects a lot of light, absorbs a little light, and transmit almost no light.
The total metabolic energy used by each to complete the course is determined as 656.91 J.
<h3>
Kinetic energy of Jessie and Jaime</h3>
The kinetic energy of Jessie and Jaime is calculated as follows;
K.E = ¹/₂mv²
where;
- m is mass of Jaime
- v is speed
15 km/h = 4.17 m/s
5 km/h = 1.39 m/s
K.E = ¹/₂(68)(4.17)² + ¹/₂(68)(1.39)²
K.E = 656.91 J
Thus, the total metabolic energy used by each to complete the course is determined as 656.91 J.
