The nature of the image depends on the position of the object which is the candle in this case.

<h3>What is a concave mirror?</h3>

A concave mirror is one of the types o curved mirror. We must note that the position and nature of the image is determined by the position of the object as shown on the ray diagram.

In this case the ray diagram is missing hence the question is incomplete. The nature of the image depends on the position of the object which is the candle in this case.

A sample of chloroform is found to contain 12.0 g of carbon, 106.4 g of chlorine, and 1.01 g of hydrogen. If a second sample of

GREYUIT [131]

Given:

Sample 1:

Chloroform is $CHCl_{3}$

12 g Carbon

1.01 g Hydrogen

106.4 g Cl

Sample 2:

30.0 g of Carbon

Solution:

mass of chloroform from sample 1:

12 + 1.01 +106.4 =119.41 g

Now, for the total mass of chloroform in sample 2:

mass of chloroform $\times$ $\frac{given mass of carbon}{mass of carbon atom}$

mass of chloroform = 119.41 $\times$ $\frac{30}{12}$ = 298.53 g

If you swing a bucket of water fast enough in a vertical circle, at the highest point the water does not spill out. This happens

amm1812

Answer:

True

Explanation:

If we swing a bucket of water fast enough in a vertical circle the water does not spill out even at the top-most position of the bucket. This happens because the centrifugal force acting away from the center in a circular motion neutralizes or overcomes the gravitational force on the water particles.

<u>Centrifugal force is mathematically related as:</u>

$F=m.r.\omega^2$

where:

m = mass of the revolving body

r = radius of revolution

$\omega=$ angular velocity in radians per second

This force F acts in radially outward direction.

If a 100-n net force acts upon a 50g car, what will the acceleration of the car be

Brrunno [24]

Answer:

2m/s

Explanation:

The formula for acceleration can be found by [ a = f/m ]

We are given the force [ 100N ] and the mass [ 50g ].

We can use these values to solve for the acceleration.

a = 100/50

a = 2m/s

Best of Luck!

A solid conducting sphere has net positive charge and radius r = 0.800 m . At a point 1.20 m from the center of the sphere, the

Serga [27]

here we have to calculate the net positive charge present on he surface of the conducting sphere.

as the sphere is a conducting one the,the charge will be stored on its surface.

though the charge is present at the surface,still it will behave just like the total charge is concentrated at the centre of the sphere.

the electric field at outside of the sphere is E= $\frac{1}{4\pi\epsilon} \frac{q}{r^2}$

as E= $\frac{-dv}{dr}$

so V= $\frac{1}{4\pi\epsilon} \frac{q}{r}$

here V=27 volt,radius of sphere is 0.800 m and the point at which the potential is considered is at 1.20 m from th centre of the sphere.hence the point is at the outside of the sphere .

hence we have 27= $\frac{1}{4\pi\epsilon} \frac{q}{1.20}$

q=27× $\frac{1}{9*10^{9} }* 1.20$ coulomb

=3.6× $10^{-9}$ coulomb [ans]
