Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it

stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that’s above the ball. Slip an end of the string through the hole, and tie a knot. This is your pendulum. Hold the loose end of the string still with one hand. With the other hand, raise the ball in an arc so that it’s almost level with the hand holding the string. With the string taut, let the ball go. What do you observe?

I observe two phenomena:

Obs-1:  I don't have the materials here to perform this experiment.

Obs-2:  You have not done the assigned experiment, and you apparently have no intention of doing it.

If the mass of Earth increased, with no change in radius, your weight<br> would
amm1812

Answer:

Increase

Explanation:

If the mass of the earth increase, with no change in radius, one's weight would also increase considerably.

The reason for this is that, the gravitational force of attraction between the two bodies will increase.

  • The gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
  • So, increasing the mass of the earth will increase the gravitational force on one's body and hence, an increase in weight.

AYUDA!!!!
xeze [42]

Answer:

4. B) 69N

5. B) 7.2kg

Explanation:

Dados los siguientes parámetros;

Masa = 7kg

Peso = 71N

La aceleración debida a la gravedad es igual a 9.8m/s².

a. Para determinar el peso de la siguiente masa;

Matemáticamente, el peso viene dada por la fórmula;

Peso = masa * aceleración debida a la gravedad

Peso = 7 * 9.8

Peso = 68.6 ≈ 69 Newton.

b. ¿Cuál es la masa sobre la tierra de un objeto que pesa.

Peso = masa * aceleración debida a la gravedad

71 = masa * 9.8

Masa = 71/9.8

Masa = 7.2 Kilograms.

Would time travel ever be possible? If so how and through what extensive process would it might be possible.
makkiz [27]

Answer:

There are two ways we may, one day, be able to time travel forwards.

You may have heard of Cryogenics. This is when someone who’s died is frozen instead of being buried or cremated. The theory is they can be “woken up” in the future when we have the technology to bring them back to life. Or a machine or device could be developed so that some people age more slowly than others around them. This way they’d live longer and see a future beyond the average person’s life span.  

Another very different way of travelling into the future is more like what you’d see in science fiction. This is might involve travelling in a rocket or spaceship at a very high speed, close to the speed of light. “We can’t establish equality with the speed of light but it is possible, in theory, to travel nearly as fast as the speed of light,” adds Dr Steane.  

So imagine you’re in a spaceship travelling very fast away from the Earth and you stay in orbit for a year. You would age at the same rate as if you were still on the Earth, by a year, but when you returned, the earth may have aged hundreds of years. “This is way beyond the technology we have at the moment,” he says. “But... in theory, it is possible.”

Explanation:

Hope this helped!

Which equation can correctly express the relation between force, acceleration, and mass?
Roman55 [17]

Hi there!

\large\boxed{\text{a) F = m * a}}

According to Newton's Second Law, force is calculated with the formula:

F = m × a, where:

F = force (N)

m = mass (kg)

a = acceleration (m/s²)

When more than one wave is in the same location at the same time, then there is _____ between the waves?
igor_vitrenko [27]
The sentence can be completed as follows:
"<span>When more than one wave is in the same location at the same time, then there is interference between the waves"

In fact, when there are two or more waves in the same location at the same time, their amplitude sum together. The two extreme possibilities are:
- costructive interference: the two waves arrive on phase at the same location (=their crests arrive at the same location at the same time). In this case, the amplitudes of the waves sum together and the resultant wave has greater amplitude.
- destructive interference: the two waves arrive out of phase at the same location. In this case, the amplitudes of the two waves cancel out, and the resultant wave has amplitude zero.</span>
