My name is Ann [436]3 years ago

Answer:

43.2^{\circ}C

Explanation:

The change in temperature of the sample of alcohol is given by:

\Delta T=\frac{Q}{mC_s}

where

Q = 890 J is the amount of heat provided to the sample

m = 16.6 g is the mass of the sample

C_s = 2.47 J/gC is the specific heat of alcohol

Solving the equation,

\Delta T = \frac{890 J}{(16.6 g)(2.47 J/gC)}=21.7^{\circ}C

And since the initial temperature was

T_i = 21.5^{\circ}C

the final temperature is

T_f = T_i + \Delta T=21.5^{\circ}C + 21.7^{\circ}C=43.2^{\circ}C

Density: Two blocks, A and B, are put in a tank of water. Block A has a density of 1.21 g/cm³. Block B has a density of 1.37 g/c
stira [4]

Answer:

Block A

Explanation:

Block A will float higher in the water compared to the second Block.

The density of water is 1g/cm³.

According to the principle of floatation "an object that floats in a liquid will displace equal amount of fluid to the weight of the object".

A body will become more submerged in water if it has more density because density is the mass per volume of  body.

An object with a higher density than another will sink in the liquid of the one with lesser density.

  • Object A has lesser density and will float higher up and displace very little water.
  • Object B has higher density and will be more submerged.

Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but have a much smaller dia
Crank

Answer:

Wn = 9.14 x 10¹⁷ N

Explanation:

First we need to find our mass. For this purpose we use the following formula:

W = mg

m = W/g

where,

W = Weight = 675 N

g = Acceleration due to gravity on Surface of Earth = 9.8 m/s²

m = Mass = ?

Therefore,

m = (675 N)/(9.8 m/s²)

m = 68.88 kg

Now, we need to find the value of acceleration due to gravity on the surface of Neutron Star. For this purpose we use the following formula:

gn = (G)(Mn)/(Rn)²

where,

gn = acceleration due to gravity on surface of neutron star = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

Mn = Mass of Neutron Star = Mass of Sun = 1.99 x 10³⁰ kg

Rn = Radius of neutron Star = 20 km/2 = 10 km = 10000 m

Therefore,

gn = (6.67 x 10⁻¹¹ N.m²/kg²)(1.99 x 10³⁰ kg)/(10000)

gn = 13.27 x 10¹⁵ m/s²

Now, my weight on neutron star will be:

Wn = m(gn)

Wn = (68.88)(13.27 x 10¹⁵ m/s²)

<u>Wn = 9.14 x 10¹⁷ N</u>

Middle school physics ​
Alecsey [184]

Answer:

8 V

Explanation:

There is no resistance between the left legs of voltmeters 2 and 3 and there is no resistance between the right legs of voltmeters 2 and 3. They are measuring the same voltage.
