Answer: Option (B) is the correct answer.

Explanation:

A process in which transfer of heat occurring when one object touches another object is known as conduction.

For example, when a pan is heated and then an egg is placed over the pan. Then there will be transfer of heat from pan towards the egg.

As a result, the egg gets cooked because the egg was touching the pan.

Hence, we can conclude that it is conduction because the egg is touching the pan.

Naddika [18.5K]

Answer:

$p =-1.03$

Explanation:

From the question we are told that:

Focal length of lens $f=-0.304 m$

Image distance $q=0.237 m$

Height of image $H_i=0.343$

Generally the lens equation is mathematically given by

$\frac{1}{f} = \frac{1}{q} - \frac{1}{p}$

Where $p$ is Subject

$p = \frac{(qf) }{(f - q)}$

$p = \frac{(-0.237)(-0.304)) }{((-0.304) - (0.237))}$

$p =-1.03$

Therefore the distance between the person and the car is

$p =-1.03$

An SUV has a mass of 6000 kg and a compact car has a mass of 2000 kg. They both go around the same unbanked circular curve on th

Evgen [1.6K]

Answer:

Therefore, the centripetal acceleration of the SUV is 3 times ao of the compact car.

Explanation:

FOR SUV:

$ac_{suv} = \frac{mv^2}{r}\\$

where,

ac_suv = centripetal acceleration of the SUV = ?

m = mass of SUV = 6000 kg

v = speed of SUV = vo

r = radius of path

Therefore,

$ac_{suv} = \frac{6000\ vo^2}{r}\\$ ---------------- equation (1)

FOR CAR:

$ao = \frac{mv^2}{r}\\$

where,

ao = centripetal acceleration of the car = ?

m = mass of car = 2000 kg

v = speed of car = vo

r = radius of path

Therefore,

$ao = \frac{2000\ vo^2}{r}\\$ --------------------- equation (2)

Dividing equation (1) by eq(2):

$\frac{ac_{suv}}{ao} = \frac{6000}{2000}\\\\ac_{surv} = 3ao$

Therefore, the centripetal acceleration of the SUV is 3 times ao of the compact car.

Before scientists come up with a scientific question, what do they have to do first?

Mademuasel [1]

Scientist would check what other scientists have said before they come up with their own scientific question. That way they can record the results from the others and compare them with their own findings when they conduct their own experiments and record the findings.

What are the Characteristics of theta waves

stiv31 [10]

When the delta brainwave frequencies increase into the frequency of theta brainwaves, active dreaming takes place and often becomes more experiential to the person. Typically, when this occurs there is rapid eye movement, which is characteristic of active dreaming. This is called REM, and is a well known phenomenon.. Hope that helps!
