Divide the force given by mass and you will find the acceleration of the object :-
F = m × a
3.63 = 18.15 × a
3.63 = 18.15a
a = 3.63/18.15
a = 0.2 m/s^2
hope it helps!
Answer:
Hey :)
Explanation:
Work is a net force applied through a distance in order to displace an object, commonly abbreviated as W. A net force is the sum of all forces acting on an object. Work is mass times acceleration and distance so to find out the work you simply calculate the acceleration of the box being brought in. Next find the distance it was carried to get in the house. Then find out the mas of the box and finally multiply those sums together to get the amount of work put in to bring the package inside.
hope this helps :) xo
Wildfires benefit grasslands, northern forests, and deciduous forests. Grasslands are benefited by improved soil quality and control of tree cover. Invertebrate species diversity is maintained through wildfire as well. Northern forests, like grasslands, experience increased production and nutritional quality of food as a result of wildfires. Deciduous forests experience an increase in the nutritional quality of food as well, but the effects are more temporary. The amount of shrubs in deciduous forests is reduced as a result of wildfires, allowing more herbaceous plants such as mosses and lichens to grow.

Your question is not complete. this option completes your question
<em> Which of the following is not a formant wavelength? </em>
<em>A. 3λ/4.
</em>
<em>B.λ /4.</em>
<em>c. λ/2 </em>
<em>D. 7λ/4</em>
Explanation:
A formant wavelength will be such that the total length of pipe = nλ/2 + λ/4.
When the above condition is satisfied then only a node is formed at the closed end and antinode at the open end.
Among the given options:
(a) 7λ/4 = nλ/2 + λ/4, satisfied for n = 3
(b) 3λ/4 = nλ/2 + λ/4, satisfied for n = 1
(c) λ/2 λ/2 = nλ/2 + λ/4, not satisfied for any value of n, HENCE NOT A FORMANT WAVELENGTH (ANSWER)
(d) λ/4 = nλ/2 + λ/4, satisfied for n = 0
Answer: 3.7×10¹²watts
Explanation:
Radiation is one of the mode of heat transfer and modes differs from each other based on their medium of heat transfer. Radiation is a process of transferring heat energy from one point to another without heating the intervening medium (no material medium is required).
According to Stefan's law of radiation, the rate of emission of radiant energy is directly proportional to the fourth power of its absolute temperature.
Mathematically, R = eAT⁴
e is constant of proportionality called emissivity. Emissivity varies depending on the type of body being considered.
For the question, we are considering black body and emissivity of black body is 1 being a perfect body.
A is the area of the body
T is the absolute temperature
e = 1
A = 0.5cm²
T = 1650°C
Rate of radiation = 1×0.5×1650⁴
= 3.7×10¹²watts.
The hole will therefore radiate 3.7×10¹²watts
