Answer:

A. When half the parent nuclei in a sample have become daughter nuclei

Explanation:

The point at which the half-life is reached is when half of the parent nuclei in a sample have become daughter nuclei.

Every radioactive atom starts with the parent. When they disintegrate they given the daughter nuclides.

The half - life is the time taken for half of the radioactive nuclei to disintegrate.

The shorter the half - life, the faster the decay process.

Answer:

the time period is 22.63 years

Explanation:

The computation of the number of years taken is as follows:

According to the Keplers law

[tex]T^2 \propto R^3[/tex]

Here T denotes the time period

And, R denotes the average distance among the sun and planet

Now let us assume for earth

R_1 & T_1 be 1 year

So, for Planet

[tex]R_2 = 8R_1 , T_2 = ?[/tex]

Now applied Keplers law

[tex](\frac{T_2}{T_1})^2 \propto (\frac{R_2}{R_1})^3\\\\(T_2)^2 = (\frac{8R_1}{R_1})^3 \times 1^2\\\\(T_2)^2 = 512\\\\T_2 = 22.674[/tex]

So, the time period is 22.63 years

Explanation:

Question 4

Force is represented using letter F

the force formula f = ma

Question 5

mass = 0.43kg

acceleration = 49.4m/s²

Force = ?

Remember that force F = ma

Now substitute, F = 0.43 × 49.4 = 21.2N

Answer:

Amplitude

Explanation:

The amount of energy a wave carries is determined by the amplitude. The larger the amplitude, the more energy the wave has, and the smaller the amplitude, the less energy the wave has.

In this case, since wave A has more energy than wave B, wave B must have a smaller amplitude than wave A.

Answer:

The work done on the concrete is 1,470,000 J

Explanation:

Given;

mass lifted by the crane, m = 3,000 kg

height through which the mass was lifted, h = 50 m

The work done on the concrete is equal to the gravitational potential energy of the concrete due to the height it was raised.

E = W = mgh

W = mgh

W = 3000 x 9.8 x 50

W = 1,470,000 J

Therefore, the work done on the concrete is 1,470,000 J

Let's find the critical points of the inequality.

−2x3511.152+5x−11=10

−2x3511.152+5x−11+−5x=10+−5x(Add -5x to both sides)

−2x3511.152−11=−5x+10

−2x3511.152−11+11=−5x+10+11(Add 11 to both sides)

−2x3511.152=−5x+21

−2x3511.152

−2=−5x+21/−2

(Divide both sides by -2)

x3511.152=5/2x+−21/2

Curves around objects

Explanation:

Diffraction is a property of light described by bending of light around an object. This ability of light to bend around edges has facilitated optical effects of light where there is interference of light waves. Other properties of light are: reflection, refraction, polarization, scattering of light, and interference of light.

Answer:

Rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body.

Answer:

★ Most of the water doesn't come from the ocean, it comes from fresh water sources

Explanation:

Hope you have a great day :)

Most of the water doesn't come from the ocean, it comes from fresh water sources.

When water vapor in the sky condenses into droplets and hits the ground, rain is created. Although saltwater does turn into water vapor during the evaporation process, freshwater makes up the droplets that form in clouds. This is so that only the salt is left behind after the process of evaporation separates the freshwater from the saltwater.

The water vapor rises and cools, forming droplets that are virtually totally composed of freshwater when they condense.

The droplets that are heavy enough to defeat evaporation and fall as rain are the ones that make it to the earth.

Precipitation is the natural method of removing salt from water and creating fresh water.

Answer:

C. A baseball bat strikes a baseball.

Explanation:

Newton's second law of motion states that acceleration happens when force is applied on the mass.

A baseball bat strikes a baseball is the best example of Newton's second law of motion because acceleration of the baseball is directly proportional to the force by which baseball bat hit it.

Hence, the correct option is 'C. A baseball bat strikes a baseball.'

Answer:

P.E = 424869.2 Joules

Explanation:

Given the following data;

Mass, m = 53kg

Height, h = 818m

We know that acceleration due to gravity, g is equal to 9.8m/s²

To find the potential energy

P.E = mgh

Substituting into the equation, we have

P.E = 53*818*9.8

P.E = 424869.2 Joules

Therefore, the potential energy of the roller coaster is 424869.2 Joules.

Answer:

the magnitude of the displacement after 5s is 137.31 m.

Explanation:

Given;

initial velocity of the projectile, u = 60 m/s

angle of projection, θ = 60°

time of motion, t = 5s

the vertical component of the velocity, [tex]u_y= u\ sin \theta = 60sin(60^0)[/tex]

The magnitude of the displacement after 5s is calculated as;

[tex]h = u_yt -\frac{1}{2} gt^2\\\\h = 60sin (60^0)\times 5 - \frac{1}{2} (9.8)(5)^2\\\\h = 259.81-122.5\\\\h = 137.31 \ m[/tex]

Therefore, the magnitude of the displacement after 5s is 137.31 m.
