Answer:

D

Explanation:

The density has a formula of d = m / V.

The volumes are given as the same.

The density will be

d_lead = 113/ V

d_aluminum = 27/V

It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.

A: incorrect. If the volumes are the same, the density is not the same because the masses are different.

B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.

C: incorrect. The exact opposite is the answer.

D: Correct. This is the answer.

Answer:

[tex]\boxed {\boxed {\sf 15 \ kg*m/s}}[/tex]

Explanation:

Momentum is the product of mass and velocity.

[tex]p=m*v[/tex]

The mass of the ball is 1.5 kilograms and the velocity is 10 meters per second.

[tex]m= 1.5 \ kg \\v= 10 \ m/s[/tex]

Substitute the values into the formula.

[tex]p= 1.5 \ kg* 10 \ m/s[/tex]

Multiply.

[tex]p=15 \ kg*m/s[/tex]

The momentum of the ball is 15 kilogram meters per second.

Answer:

15 kg m/s

Explanation:

[tex]p = mv \: = 1.5 \times 10 = 15 \: kgm {s}^{ - 1} [/tex]

Answer the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets

Answer:

Thermal heat

Explanation:

The water heats up which it means it is thermal (heat/hot)

Solution :

Using the Gauss law, the electric field intensity of a sphere is given by :

[tex]$E. 4 \pi r^2 = \frac{Q_{enc}}{\epsilon_0}$[/tex]

[tex]$E = \frac{Q_{enc}}{4 \pi r^2 \epsilon_0}$[/tex]

Now the enclosed charge inside the sphere (r<a) is

[tex]$Q_{enc}= \rho V$[/tex]

[tex]$Q_{enc}= \rho \left( \frac{4}{3} \pi r^3 \right)$[/tex]

Hence, the electric field intensity becomes as follows :

[tex]$E= \frac{\rho \left(\frac{4}{3} \pi r^3\right)}{4 \pi \epsilon_0 r^2}$[/tex]

[tex]$E =\frac{\rho r}{3 \epsilon_0}$[/tex]

Thus, the electric field inside the sphere is given by :

[tex]$\vec {E} = \frac{\rho \vec{r}}{3 \epsilon_0}$[/tex]

Answer:

5.6m

Explanation:

given

Applied force(F)=625N

workdone(w)=3500J

distance travelled by wheel barrow(s)=w/F

= 3500/625

= 5.6m

Answer: 144 g

the mol of the oxygen gas is 64/16 = 4 (mol)

we have:

2H2 + O2 => 2H2O

           4  ------> 8

=> the mol of H2O is 8 mol

=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)

The measure of life in hours and wind is my enemy states that is a candle as it states I serve you by expiring.

A candle is a stick made of wax and forms an inflammable solid substance. It has a light and gives some sort of fragrance.

It can also provide a medium to heat or to save time, as the candle is burnt the oxygen is consumed and carbon id is given out. As the statement speaks about the wind which is my enemy, it states the nature of the candle that dies out immediately.

Answer:

190 kg m/s

Explanation:

Momentum = Velocity × Mass

→ Substitute in values

2 × 95 = 190 kg m/s

The momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

Momentum is defined as the product of mass of velocity. Momentum is a vector quantity. Mathematically, we can write momentum as -

p = mv

It is also the measure of the impact force imparted by any moving object, when it comes in contact with some other body.

Given is a boat with a mass of 95 Kg moving at 2 m/s.

Mass [m] = 95 Kg

Velocity [v] = 2m/s

We can write the momentum as -

p = mv

Substituting values, we get -

Momentum [p] = 95 x 2 = 190 Kg m/s

p = 190 Kg m/s

Therefore, the momentum of the boat of mass 95 Kg moving at 2 m/s will be 190 Kg m/s.

Answer:

a) reactant

b) product

Explanation:

During a chemical reaction, the reactants interact among themselves in a specific temperature, pressure, pH, enzyme etc. Due to various intra and inter molecular and atomic interactions, the chemical bonds in the reactants break down. Formation of new chemical product is governed by the formation of new bond (ionic, covalent, hydrogen vander waal etc. )

Answer:

350J

Explanation:

Given parameters:

Weight of bag  = 20N

Distance moved horizontally  = 35m

Force applied  = 10N

Unknown:

Work done on the bag  = ?

Solution:

Work done is the force applied to move a body through given distance.

  Work done  = Force applied x distance

So;

 Work done  = 10 x 35  = 350J

Answer:

the initial velocity is 20 m/s   and  the acceleration is 2 m/s²

Explanation:

Given equation of motion, v = 20 + 2t

If V represents the final velocity of the object, then the initial velocity and acceleration of the object is calculated as follows;

From first kinematic equation;

v = u + at

where;

v is the final velocity

u is the initial velocity

a is the acceleration

t is time of motion

If we compare  (v = u + at)   to     (v = 20 + 2t)

then, u = 20    and  

         a = 2

Therefore, the initial velocity is 20 m/s   and  the acceleration is 2 m/s²

Answer:

separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.

Answer:

Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate.
