Answer:
534 j
Explanation:
100 lbs = 45.359 kg
work = F * d
= 45.359 * 9.81 * 1.2 = ~ 534 j
Answer:
2nd answer 3.2m/s is a scalar l, all others are vectors.
Explanation:
In order to be considered as a vector a certain quantity must have both a magnitude and a direction.
The most common example is velocity. It has both magnitude and direction, like the 1st and the last answers.
The 3rd answer is an acceleration. It is also given with its direction. So we have to consider it also as a vector.
But 2nd answer has no direction mentioned, so it is considered as a scalar.
Answer:
1. inference
2. analysis
others I don't have any idea sorry
Answer:
Temperature of the object
Explanation:
According to kinetic theorem of gases, the temperature of a gas is a measure of the of the average kinetic energy of the gas particle.
A particle can either exist as solid, liquid or gas.
For solid, the particles are fixed as they rotates and vibrate about a mean position.
The particle of an object is a solid particle.
In accordance to kinetic theorem, the temperature of an object related to the average kinetic energy of the particles in the object.\
Temperature: This can be defined as the degree of hotness or coldness of an object.
Answer:
The correct option is thermogram
Explanation:
A thermogram is an image that is produced by thermographic cameras that are usually used to detect radiation (thermal energy released by a body) within a long-infrared range of electromagnetic spectrum. This process is a part of infrared imaging science which is useful in the diagnosis of breast cancer and some other forms of tumors.
