Answer:

I. 56

II. c is the speed of light in vacuum.

III. 385.180×10¯²⁷ Kg.

Explanation:

I. Determination of the value of p.

²³⁸₉₂U + ¹₀n —> ¹³⁹ₚBa + ⁹⁷₃₆Kr + 3 ¹₀n

92 + 0 = p + 36 + 3(0)

92 = p + 36

Collect like terms

92 – 36 = p

56 = p

Therefore, the value of p is 56

II. Determination of the meaning of c

ΔE = Δmc²

In the Einstein's equation above,

E => is the energy

m => is the mass

c => is the speed of light in vacuum.

III. Determination of the total mass of the element formed after the reaction.

From the reaction above, the elements formed after the reaction are:

Barium–139 and Krypton–97. Thus, we can obtain the total mass of the elements formed as follow:

Mass of Ba–139 = 232.560×10¯²⁷ Kg

Mass of Kr–97 = 152.620×10¯²⁷ Kg

Total mass =?

Total mass = mass of Ba–139 + mass of Kr–97

Total mass = 232.560×10¯²⁷ + 152.620×10¯²⁷

Total mass = 385.180×10¯²⁷ Kg

Answer:

d = 493.72 m

Explanation:

Given that,

Initial velocity of the train, u = 80 km/h = 22.22 m/s

Acceleration of the train, a = -0.5 m/s² (negative as it slows down)

Finally brakes are applied, v = 0

We need to find the distance the train travels. Let the distance be d. Using third equation of kinematics to find it.

[tex]v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{0^2-(22.22)^2}{2\times (-0.5)}\\\\d=493.72\ m[/tex]

So, the required distance is equal to 493.72 m.

Answer: e) turbidity​

Explanation:

Evaporation is  defined as the process by which a liquid without being heated is converted into vapor.

The factors that affect the rate of evaporation of a liquid are:

a) humidity-When the humidity of an environment is high, it will take more time for water to escape to the atmosphere and less time, if the reverse is the case because Humidity is the amount of water vapor in the atmosphere. For example, on a rainy day, clothes tend to dry slower than a sunny day.

b) nature of liquid- different liquids have different rate of evaporation, For example, alcohol will evaporate faster than water

c) pressure - The higher the pressure  on the surface of a body of water, the slower the  evaporation rate and vice versa.

d) temperature- The temperature of a surrounding affect how fast a liquid ,(water) can evaporate. When the temperature of the liquid  is increased, it raises the kinetic energy of the individual molecules that make up the liquid thereby reducing the inter molecular forces of attraction holding the liquid together and causing fast  escape into the atmosphere as a vapor or gas

e) turbidity​  shows the extent water loses its transparency due to the presence of suspended particles lie clay, silt, organic matter etc and so is not a factor that affect rate of evapouration

The incorrect part of the chart is;

Line 1

Chemical [tex]{}[/tex] Reaction   [tex]{}[/tex]                                   Nuclear Reaction

Line 1 Happens in the nucleus of atoms   [tex]{}[/tex] Happens between atoms

Explanation:

The given chart can be presented as follows;

  Chemical Reaction [tex]{}[/tex]                               Nuclear Reaction

1. Happens in the nucleus of atoms    [tex]{}[/tex]   Happens Between atoms

2. Forms new compounds [tex]{}[/tex]                     Forms new atoms

3. Involves small amounts of energy [tex]{}[/tex]    Involves large amounts of energy

From the above chart, line 1 is incorrect because a chemical reaction happens between the valence electrons of the reacting atoms while a nuclear reaction is the reaction that takes place between the nucleus of two or more atoms or the nucleus of an atom and a subatomic particle to produce one or more than new nuclide of a new atom with a change in the mass of the nucleus being represented by the large amount of energy in the reaction. Therefore, a nuclear reaction takes place in the nucleus of an atom, forms new atoms and involves large amounts of energy

Answer:

71344 J

Explanation:

From the law of conservation of energy,

Mechanical Energy = Kinetic Energy + Potential Energy

M.E = (mv²/2)+ mgh.................... Equation 1

Where M.E = Mechanical Energy, m = mass, v = Velocity, h = height, g = acceleration due to gravity.

Given: m = 52 kg, v = 28 m/s, h = 100 m (half way down the ski jump)

Constant: g = 9.8 m/s²

Substitute these values into equation 1

M.E = (52×28²/2) + (52×100×9.8)

M.E = 20384+50960

M.E = 71344 J

Explanation:

Answer:

The correct answer is "0.32 mL".

Explanation:

The given values are:

Density of gold bar,

d = 19.3 g/mL

Mass of gold bar,

m = 6.3 grams

Now,

The volume will be:

⇒  [tex]Density = \frac{Mass}{Volume}[/tex]

or,

⇒  [tex]Volume=\frac{Mass}{Density}[/tex]

On substituting the values, we get

⇒               [tex]=\frac{6.3 \ g}{19.3 \ g/mL}[/tex]

⇒               [tex]=0.32 \ mL[/tex]

Answer:

the small one will have greater acceleration

Explanation:

force and mass are inversely proportional. force and acceleration are directly proportional. which means greater mass have smaller acceleration and smaller mass has greater acceleration. this is due to newtons second law of motion.

The small object will have greater acceleration as compared to a heavy truck if we push with the same amount of force, i.e., 7000 N.

Acceleration is proportional to change in velocity.

When there will be a change in velocity with time, that is called acceleration.

[tex]\vec{a}[/tex]=[tex]\vec{dv}/dt[/tex] where,

[tex]\vec{a}[/tex] is the acceleration,

[tex]\vec{dv}[/tex] is the change in velocity and,

dt is change in time.

It is a vector quantity.

SI unit of acceleration is [tex]m/s^{2}[/tex].

There are several types of acceleration :

As we know that acceleration depends on the change in velocity and velocity of a body depends on the mass of the body. So if the body has less mass it must have a higher velocity and if it has a higher velocity than it has  greater acceleration.

Hence, the small object/body has greater acceleration as compared to a heavy truck.

Answer:

4

Explanation:

Velocity ratio is the ratio of distance moved by effort to the ratio of distance moved by load

Velocity ratio = Distance moved by effort / Distance moved by load

Distance moved by effort = 20m

Distance moved by load = 5m

20m / 5m = 4

Answer:

151.2 m/s

Explanation:

m1 = 0.020 kg

m2 = 2.5 kg

vf = 1.2 m/s

m1v1 +m2v2 = (m1 +m2)vf

0.020v1 + 0 = (0.020 +2.5)(1.2)
