Answer:
In a simplest terms,
temperature is how hot or cold an object is, while heat is the energy that flows from a hotter object to cooler one
<em>Power = (voltage) x (current)</em>
We don't actually know what power<em> rating</em> may be marked on the bulb or the package it comes in, but the power it actually consumes and dissipates, when connected to a 15V battery, is . . .
Power = (15 V) x (3.0 A) = <em>45 watts</em>
Answer:
11.27N
Explanation:
Given parameters:
Mass of the book = 1.15kg
Unknown:
Magnitude of the normal force = ?
Solution:
The normal force is the vertical force exerted by a body on an object.
It can be described as the weight of an object.
Normal force = mass x acceleration due to gravity
Normal force = 1.15 x 9.8 = 11.27N
To provide a greater certainty that the observed results are not by chance.
