Answer:

B. 2K + Br2 + 2KBr

D. C + 02 → CO2

Explanation:

In balancing a chemical reaction, the number of atoms on both sides of the expression must be the same in order to obey the law of conservation of mass.

According to the law of conservation of mass, in a chemical reaction, matter is neither created nor destroyed.

 So, let us investigate:

                                                 Number of atoms

                            Reactants                                        Products

K                                  2                                                      2

Br                                 2                                                      2

C + 0₂ → CO₂

C                                1                                                        1

O₂                              2                                                      2

We see that for both equations, the number of atoms on both sides of the expression is the same.

Answer:

The thermic effect (TEF) is greater for protein compared to carbohydrate and fat. The body can store excess amino acids for later use. The protein-sparing effect spares the utilization of protein as an energy source and allows it to be used for more important metabolic functions.

Answer: The statement when the motion energy of an object changes, energy is being transferred is true.

Explanation:

Motion energy is also called mechanical energy and it is the summation of kinetic energy and potential energy stored in an object required for work.

As kinetic energy is the energy acquired due to motion of an object and potential energy is the energy acquired by an object due to its position.

For example, when a moving ball strikes another ball causing it to move then energy is being transferred from one ball to another.

Therefore, the statement when the motion energy of an object changes, energy is being transferred is true.

Answer:

Most coastal areas, with some exceptions, experience two high tides and two low tides every lunar day (Ross, D.A., 1995). Almost everyone is familiar with the concept of a 24-hour solar day, which is the time that it takes for a specific site on the Earth to rotate from an exact point under the sun to the same point under the sun. Similarly, a lunar day is the time it takes for a specific site on the Earth to rotate from an exact point under the moon to the same point under the moon. Unlike a solar day, however, a lunar day is 24 hours and 50 minutes. The lunar day is 50 minutes longer than a solar day because the moon revolves around the Earth in the same direction that the Earth rotates around its axis. So, it takes the Earth an extra 50 minutes to “catch up” to the moon (Sumich, J.L., 1996; Thurman, H.V., 1994).

Answer:

a = 1.49m/s²

Explanation:

Find the diagram attached  

According to Newton's second law of motion

\sum Fx = ma

Fm - Ff = ma

Fm is the moving force

Ff is the frictional force

Fm = Wsin theta

Ff = μR = μWcos theta

Wsin theta - μWcos theta = ma

W is the weight = 50.1 * 9.8 = 490.98N

theta is the angle of inclination = 27.2°

μ is the coefficient of friction = 0.343

m is the mass = 50.1kg

a is the acceleration  

Substitute into the formula as shown;

Wsin theta - μWcos theta = ma

490.98sin27.2° - 0.343(490.98)cos 27.2° = 50.1a

224.423 - 149.78 = 50.1a

74.64 = 50.1a

a = 74.64/50.1

a = 1.49m/s²

Hence the acceleration of the block is a = 1.49m/s²

Answer:

15 KJ

Explanation:

The quantity of heat (Q) required is given as:

Q = mcΔθ + mL

where m is the mass of ice, c is its specific heat capacity, L is its specific latent heat andΔθ is the change in temperature.

Given: m = 20g, temperature of ice = 0[tex]^{o} C[/tex], specific heat capacity of water = 4200 J/kg[tex]^{o} C[/tex], latent heat of fusion of ice = 3.3 x 10^(5) J/kg, temperature of water = 100[tex]^{o} C[/tex].

Q = m (cΔθ + L)

   = 0.02(4200 x (100) + 330000)

   = 0.02(420000 + 330000)

  = 0.02 (750000)

Q = 15000

Q = 15000 Joules

Q = 15KJ

The quantity of heat needed to complete the conversion is 15 KJ.

  [tex]\omega ^2= \frac{9.8}{30}[/tex]

 [tex]\omega = \sqrt{\frac{9.8}{30}}[/tex]

 [tex]\omega= 0.571 rad/s[/tex]

Therefore solving for  Period T

Generally the equation for solving Period T is mathematically given as

 [tex]T= \frac{2\pi}{\omega}[/tex]

Answer:b.outward in a straight line tangent to the circle!

Explanation:at any given point on the circle is always along the tangent line.

Answer:

(i) The acceleration of the object down the plane is approximately 4.9 m/s²

(ii) The time it takes for the object to reach the bottom is approximately [tex]1.\overline{428571}[/tex] seconds

(iii) The time it takes the object to come to rest is approximately 1.030636 seconds

(iv) The object has travelled past the top of the plane by time it comes to rest

Explanation:

(i) The given parameter for the objects motion are;

The angle of inclination of the plane with the horizontal, θ = 30°

The length of the plane, s = 5 m

Let "a" represent the acceleration down an inclined plane, due to the acceleration under gravity "g" we have;

a = g × sin(θ)

Where;

g = The acceleration due to gravity ≈ 9.8 m/s²

∴ a ≈ 9.8 m/s² × sin(30°) = 9.8 m/s² × 0.5 = 4.9 m/s²

The acceleration of the object down the plane, a ≈ 4.9 m/s²

(ii) The time it takes for the object to reach the bottom, can be found from the following kinematic equation of motion;

s = u·t + 1/2·a·t²

Where;

s = The length of the inclined plane = 5 m

u = The initial velocity of the object = 0 m/s

t = The time of motion of the object (Here the time to reach the bottom of the plane)

a = The acceleration of the object = 4.9 m/s²

Therefore, we have;

5 = 0 × t + 1/2 × 4.9 × t² = 2.45·t²

t² = 5/2.45 = 100/49

t = √(100/49) = 10/7 = [tex]1.\overline{428571}[/tex]

The time to reach the bottom of the plane = t = [tex]1.\overline{428571}[/tex] seconds

(iii) When the object is thrown up the plane with an initial velocity of 15 m/s, the time, "t", it takes the object to come to rest is found by the following kinematic equation of motion;

v² = u² - 2·a·s

Therefore, we have;

v² = 15² - 2 × 4.9 × 5 = 176

v = √176 = 4·√11

The velocity of the object at the top of the plane = v = 4·√11 m/s

The time it takes the object to come to rest after reaching the top of the plane = The time it takes the object (projectile) to reach maximum height

[tex]t_m = \dfrac{v_i \cdot sin(\theta _i )}{g}[/tex]

Where;

[tex]t_m[/tex] = The time it takes the object to reach maximum height

[tex]v_i[/tex] = The initial velocity of the object at the top of the inclined plane = 4·√11 m/s

[tex]\theta _i[/tex] = The initial angle of inclination of the path of the object with the horizontal = 30°

Therefore, we have;

[tex]t_m = \dfrac{4 \times \sqrt{11} \times sin(30^{\circ} )}{9.8} = \dfrac{10 \cdot \sqrt{11} }{49} \approx 0.67686[/tex]

The time it takes the object to come to rest after reaching the top of the plane = The time it takes the object to reach maximum height = [tex]t_m[/tex] ≈ 0.67686 seconds

The time it takes the object to reach the top of the plane, [tex]t_{top}[/tex], is given from the kinematic equation of motion, v = u - a·t, as follows

v = u - a·t

∴ t = (u - v)/a

[tex]t_{top}[/tex] = (15 - 4·√11)/4.9 ≈ 0.353776

The time it takes the object to reach the top of the plane = [tex]t_{top}[/tex] ≈ 0.353776 s

The total time it takes the object to come to rest, ∑t = [tex]t_m[/tex] + [tex]t_{top}[/tex]

∴ ∑t ≈ 0.67686 + 0.353776 = 1.030636

The time it takes the object to come to rest = ∑t ≈ 1.030636 seconds

(iv) The distance up the plane the object reaches, "s", is given by the following kinematic equation;

s = u·t - 1/2·a·t²

Therefore, we have;

s = 15 × 15/4.9 - 1/2 × 4.9 × (15/4.9)² ≈ 22.959 m

However, the plane is 5 meters long, therefore, the object goes further than the top of the plane.

F = m*a

a = F/m

a = 39.28N/49kg

a = 0.8 m/s^2

Answer:

-1.24 m/s

Explanation:

Total momentum before collision = total momentum after collision

Total momentum before collision = (mass of full back * velocity of fullback) + (mass of lineman * velocity of line man).

Mass of full back = 112 kg, mass of line bag = 120 kg, velocity of full back  6 m/s (east), velocity of line back = -8 m/s (west). Hence:

Total momentum before collision = (112 * 6) + (120 * -8) = 672 - 960 = -288 kgm/s

The total momentum after collision = (mass of full back + mass of line back) * velocity after collision.

Let velocity after collision be v, hence:

The total momentum after collision = (112 + 120)v = 232v

Total momentum before collision = total momentum after collision

-288 = 232v

v = -288 / 232

v = -1.24 m/s

Therefore after collision, the two players would move at a velocity 1.24 m/s west (the same direction as the lineman).
