What is the velocity at 10 seconds? PLEASE HELP!!!!!

Answer:

First you calculate the distance covered in First 3hrs then calculate the time for the remaining distance then add the total time

Considering the change of units and rule of three, the number of tablets in the bottle is 2,000.

First of all, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 0.5 kg. You can see that the measurements are in different units of measurement, so you must make a change of units so that they are in the same units.

So, knowing that 1 kg is equal to 1,000,000 mg, you can apply the following rule of three: if 1 kg is equal to 1,000,000 mg, 0.5 kg is equal to how many mg?

1 kg ⇒ 1,000,000 mg

0.5 kg ⇒ x mg

So: [tex]x=\frac{0.5 kgx1,000,000 mg}{1 kg}[/tex]

x= 500,000 mg

Then, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 500,000 mg. Now that the values ​​are in the same units, to calculate the number of medicinal tablets you must apply the following rule of three: if 1 tablet has a mass of 250 mg, how many tablets have a mass of 500,000 mg?

[tex]number of medicinal tablets=\frac{500,000 mgx1 tablet}{250 mg}[/tex]

number of medicinal tablets= 2,000

Finally, the number of tablets in the bottle is 2,000.

Answer: a tadpole is the first or second step into the evolution for a frog

Explanation: a frog starts with the egg then it becomes a tadpole for 6 to 12 weeks before it can start going out the water.

Answer:

Tadpoles are baby frogs. The tadpole looks like a frog with a tail and becomes a froglet around 12 weeks after hatching. The tadpole becomes an adult frog around 13 to 16 weeks after hatching.

1. Nuclear fusion of hydrogen into helium occurs in the core.

2. Energy moves through the Sun's Convection Zone by means of the rising of hot gas and falling of cooler gas.

3. Nearly all the visible light we see from the Sun is emitted from the Photosphere.

4. Most of the Sun's ultraviolet light is emitted from the narrow layer called the Chromosphere where temperature increases with altitude.

5. We can see the Sun's Corona most easily during total solar eclipses.

6. The Radiation Zone is the layer of the Sun between its core and convection zone.

the correct answer will be 6.82 %that is 7%

p(1.27)-q(0.83) =x=0.44

0.02+0.01 =0.03 (maximum uncertainty)

percentage uncertainty =0.03/0.44×100 %

Explanation: it was d on my end

Answer:

It must return at the same velocity with which it was thrown or else there would be a preferred direction of motion leading to perpetual motion.

a = (v2 - v1) / t = (v2 - 0) / 2 = v2 / 2    for a falling object

v2 = 2 a = 2 sec * 9.8 m/sec^2 = 19.6 m/s

You can check with

H = V0 t - 1/2 g t^2      (V0 and g are in different directions)

H = 0

V0 = 1/2 g * 4 = 19.6 m/s

Answer:

visible region

Explanation:

According to the procedure in section 2, in visible region the data collected on hydrogen and helium’s line spectra.

Electromagnetic spectrum are the wave which is form of energy and includes the waves such as radio waves, gamma waves, visible light waves etc.

An element’s line spectrum can include emissions at wavelengths throughout the electromagnetic spectrum including ultraviolet, visible, and infrared.

Types of electromagnetic spectrum-

The hydrogen line spectra fall between wavelength, 410 nm to 656 nm. The helium line spectra fall between wavelength, 400 nm to 781 nm.This two fall in the visible region of line spectra.

According to the procedure in section 2, in visible region the data collected on hydrogen and helium’s line spectra.

Answer:

Traveled north = 18 blocks

Traveled east = 10 blocks

Traveled south = 16 blocks

So total distance = (18+10+16) blocks = 44 blocks

as north and south are opposite

so traveled displacement from up to down is = (18-16) blocks = 2 blocks

and starting to east distance is 10 blocks

so using pythagoras theorem the displacement

= [tex]\sqrt{10^{2}+2^{2} }[/tex] blocks

= [tex]\sqrt{104}[/tex] blocks

= [tex]2\sqrt{26}[/tex] blocks

= 10.198 blocks (approx.)

ANS: distance=44 blocks, displacement=10.198 blocks (approx.)

Answer:

50 [m/s].

Explanation:

1) formula is: V-V₀=g*t, where V₀ - final velocity (it is 0), V - required initial velocity, g≈10 [m/s²] and t - elapsed time.

2) according to the formula above:

V=g*t; ⇒ V=5*10=50 [m/s].

This is the formula and is the main step to learning about how to figure out the centripetal acceleration and force from mass and radius.

Answer:

Surface tension is the result of water molecules pulling inward with a strong attractive force. This attractive force brings the molecules on the surface of the water close together and causes the surface of the water to be drawn toward the water molecules beneath the surface. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.
