1 watt = 1 joule per sec
11,000 Watts = 11,000 joules per sec
The frequency doesn't matter.
I’m pretty positive that it’s A. Conduction. Just refer to the definition of it.
Answer: F = 102141N
Explanation: <em><u>Newton's 2nd Law</u></em> states that a force can change the motion of a body. The relation is given by
F = m.a
whose units are:
[F] = N
[m] = kg
[a] = m/s²
Jenny's car, at the moment of the break, had acceleration:
a = 78.57 m/s²
Then, Force is
F = 1300*78.57
F = 102141 N
<u>Jenny's car experienced a force of </u><u>magnitude 102141N.</u>
Answer:
Gravity creates stars and planets by pulling together the material from which they are made.
Explanation: Thats the only thing i have im stuck on the tga quiz
Answer:
Statement 1 can be matched with option f (Van der waal forces)
Statement 2 can be matched with option b (Liquid crystal)
statement 3 can be matched with option e (Thermal expansion)
Statement 4 can be matched with option g (Viscosity)
Statement 5 can be matched with option b (Fractional distillation)
Statement 6 can be matched with option a (Diffusion)
Statement 7 can be matched with option d (Miscible)
Explanation:
- Van der waal forces are weak inter-molecular bonds found between covalent molecules e.g molecules of graphite, noble gases etc
- Liquid crystals are substances that behave like liquids and its molecules orientate itself like a crystal (solid). They can be referred to as LCs.
- Thermal expansion is a phenomenon where by matter changes in shape, volume and area due to a change in temperature.
- Viscosity is a term used to describe a fluid's resistance to flow. It is also used to describe the internal friction that a moving liquid experiences. Oil is more viscose than liquid water
- Fractional distillation is a separation technique used in separating two or more miscible liquids of close boiling points. For example petrol and diesel oil can be separated using fractional distillation. An industrial application of this technique is Fractional distillation of crude oil where crude oil is separated into its components
- Diffusion is the movement of dissolved particles, gases, liquid from a region of higher concentration to a region of lower concentration until there is a equal balance. This can occur when you spray a perfume in one end of a room. You will get to smell the perfume at the other end after some time. Diffusion is fastest in gas as compared to liquids and solids.
- Miscible is a word used to describe liquids forming a homogeneous mixture when dissolved in each other. Miscibility is factor to be considered when separating mixture.
