Answer:

Beta particle

Explanation:

If an alpha particle and a beta particle have the same energy, beta particle will penetrate farther into an object than alpha particle because;

1. In air, beta particles can travel a few hundred times farther than alpha particles.

2. Beta particles have more penetrating power than alpha particles.

3. Alpha particle can be absorbed or stopped by an inch or less 1-2 centimeters of air or a thin piece of tissue while beta particles can be stopped or absorbed by a thin layer of Aluminium.

4. Alpha particles loose all of their energies in a small volume easily that beta particles.

5. Beta particles can traveled a longer distance between 2-3 meters at a speed nearly equal to that of light than alpha particles which travel a distance between 2-4 cm at a speed approximately five percent the speed of light.

Many scientists are involved in research studying global climate change. Which limitation to climate research could

dedylja [7]

Answer:

Data from a wide range of time periods must be analyzed.

Explanation:

The limitation to climate research that could easily be solved is that data from long periods of time can be analyzed. We can only gauge this based on history. So the earlier we can get super computers with greater capabilities, then the more likely it is that data from long period ranges can be analyzed. This would provide scientist with knowledge of the extent and prevention of global climate issues.

The other problems listed may not easily be solved compared to this.

Sebuah lilin diletakkan di depan lensa cembung. Bayangan maya yang dihasilkan 1,2 kali tinggi benda. Jarak benda ke lensa 5 cm.

ANEK [815]

Answer:

Focal length of the convex lens is 2.72 cm

Explanation:

As we know that the convex lens produce 1.2 times magnified image

Now we know that the object distance from the lens is 5 cm

so we have

$\frac{d_i}{d_o} = 1.2$

now we have

$d_i = 1.2 \times 5 = 6 cm$

now by the formula of lens

$\frac{1}{6} + \frac{1}{5} = \frac{1}{f}$

$f = 2.72 cm$

PolarNik [594]

Answer:

Explanation:

we need the to know the extra weight Eric has over Tom. To do that we need to subtract Tom's weight from Eric's, but now we do not know what Eric's weight is or Tom's weight. the only clue we have is that Eric is 4 inches taller than Tom

1. if Eric is 4 inches taller that Tom, then

let

Tom's height be $T_{h}$

and

Eric's height will be 4 inches more

$T_{h} +4$

let's plug these two information into the formula given in the question

for the difference in their weight;

Eric's weight will be;

w = $4.5(T_{h} +4)-154$

Tom's weight will be

w = $4.5h-154$

taking the difference between the two expressions above

w = $[4.5(T_{h} +4)-154]-[4.5h-154]$

opening the bracket

w = $4.5T_{h} +18-154-4.5h+154$

w = 18 pounds

so Eric's weight is 18 pounds more than Tom's

Compare a wave that has a period of 0.03 second with a second wave that has a period of 1⁄4 second. Which wave has the greater f

yaroslaw [1]

Answer:

The wave with 0.03 time period have the greater frequency

Explanation:

Given in the question,

Period T $_{1}$ of one wave = 0.03 seconds

Period T $_{2}$ of another wave = 1/4 seconds

We know that

T = 1 / f

So,

f $_{1}$ = 33.3 hz

f $_{2}$ = 4 hz

The wave with 0.03 time period have the greater frequency.

How could you increase the gravitational potential energy between yourself and the Earth?

pogonyaev

Answer :

Gravitational Potential Energy, GPE = mgh

Where m is your mass in kg, g is acceleration due to gravity = 9.8 m/s², and h is the height in m.

The only value that be controlled here is the height h. The mass is constant, and acceleration due to gravity at that place is constant.

But h can be varied.

Hence to increase the gravitational potential energy between yourself and Earth is to increase the height h.

This can be done by climbing up a table, or climbing up a building through the stairs, or by using a lift.
