Answer:

The biggest advantage of Solar cookers is their eco-friendliness. By exploitation one you’ll decrease your dependence on gas or electricity, cut back your carbon footprint, and save on fuel and therefore the value of fuel on running home appliances. change of state with star cookers clearly needs daylight, that makes it troublesome to use throughout winter months and on rainy days. change of state conjointly takes a considerably longer time compared to traditional strategies. Users should schedule their change of state time and maximize the employment of daylight. As a result, preparation should begin early within the morning in order that the food may be placed in the cooking utensil by noontide.

These answers are very good. I made a 95% by using this as my answer key, but unfortunately, one of these is wrong. I don't know which one, all I know is that I got 19/20. Just wanted to throw that out there. :-) Good job, Sadaqasalaam3. And thank you.

A swimmer swims north at 0.10 m/s relative to still water across a river that flows at 0.25 m/s from east to west. Calculate the

ValentinkaMS [17]

0.15 m/s East
If you follow the equation a=vf-vi/t, you'll discover that subtracting the final velocity, 0.25 m/s, by the initial velocity, 0.10 m/s, and divide by zero, (bc there was no given time) the answer is 0.15 m/s East

Which electromagnetic wave has wavelengths just longer than visible light? A. infrared radiation B. ultraviolet radiation C. mic

Nady [450]

Answer:

The correct answer is A and B

Explanation:

Light is part of the spectrum of electromagnetic energy along with radio waves, microwaves, infrared, visible light, ultraviolet, X rays and Gamma rays.

Radio waves and microwaves lie on one end of the spectrum, the longer end of electromagnetic energy.

X rays and Gamma rays have very short wavelengths .

A 7.80 g bullet moving at 530 m/s penetrates a tree trunk to a depth of 5.40 cm. (a) Use work and energy considerations to find

True [87]

Answer:

a) F=20287.22N

b) t=2*10^-4s

Explanation:

E=1/2*m*v^2=0.5*7.8*10^-3kg*(530m/s)^2=1095.51J

The frictional force's work must be equal than the energy to stop the bullet.

So: W=F*d=F*0.054m=1095.51J, F=20287.22N

Considering the frictional force is constant, the bullet moves with constant aceleration.

a=F/m=20287.22N/7.8*10-2kg=2.6*10^6m/s^2

then d(t)=Vt-1/2*a*t^2,

5.4*10^-2m=530m/s*t-1.3*10^6m/s^2*t^2

I will calculate the time using the cuadratic formula:

$\frac{-b+-\sqrt{b^{2}-4ac } }{2a}$

with a=1.3*10^6, b=-530, c=5.4*10^-2

t=2*10^-4s

Two identical conductors have charge -1.8 C and 5.5 C on them, respectively. They are connected by a conducting wire for a short

Aleks04 [339]

Answer: 1.85 C

Explanation:

Given

charges on the conductors are $-1.8\ C$ and $5.5\ C$

They are connected by a conducting wire for a short period of time and then disconnected. During this time charge flow from the wire and net charge becomes $5.5-1.8=3.7\ C$

This charge will be equally distribute among the two conductors i.e. 1.85 C on each conductor.
