Answer:
F = M a fundamental Newton's equation
F = 3 kg * 3 m/s^2 = 9 kg m / s^2 = 9 Newtons

- <u><em>Using thermal imaging to detect heat energy loss through the roof and windows.</em></u>
<u><em></em></u>
Explanation:
<em>Heat energy</em> is transmitted by conduction, convection, and <em>radiation</em>.
All warm objects emit heat energy in the form of infrared <em>radiation</em>, which is a kind of invisible light (light with a lower frequency and longer wavelentgh than the visible light).
The amount of heat energy emitted by an object is proportional to its temperature: the higher the temperature of the object body, the greater the amount of radiant energy emitted.
A<em> house </em>can loss heat energy by radiation through the walls, <em>roof and windows.</em>
<em>A thermographic camera or thermal imaging camera </em>will detect the infrared radiation emitted through walls, roof and windows, showing a red image in those areas.
I found the image attached in internet, showing the red areas around the roof and windows of a house, mainly, using a thermal imaging camera.
Answer is C. Light is measured by its wavelength (nanometers) or frequency (hertz).
Answer: The acceleration of 28 Kg object will be 2
Explanation: Force acting on an object is defined as mass times acceleration acting on it.
Mathematically it is defined as:
Force = mass acceleration
F = 8 7 = 56 N
If the same force is acting on a 28 Kg object then the acceleration of the object will be equals to force to mass ratio.
Acceleration = = 2
