I NEED HELP ASAP



Since the investigative question has two variables, you need to focus on each one separately. Thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? Use the format of "if…then…because…” when writing your hypothesis.

I NEED HELP ASAPSince The Investigative Question Has Two Variables, You Need To Focus On Each One Separately.

Answers

Answer 1

Explanation:

The formula of kinetic energy is K.E= m[tex]v^{2}[/tex]/2 , where m is the mass and v is the velocity. According to the formula, if we double the mass, the kinetic energy will also double then we can say the Kinectic energy is directly proportional to the mass.

Answer 2

Answer:

Sample Response: If the mass of an object increases, then its kinetic energy will increase proportionally because mass and kinetic energy have a linear relationship when graphed.

Answer:

ok

Explanation:

Acceleration is defined as the rate of change of velocity.

Acceleration = (Change in velocity) / time taken

Acceleration = (Final velocity - initial velocity) / time

As the object velocity changes by the same amount in each second, it means the acceleration is constant.

How can a simulation study be used to learn about a planet we have never visited?
In a simulation study you imitate some conditions and characteristics of the real planet. The simulation can be used as a substitute for real data collected on the planet.
Simulation studies can be used for planets we have already visited.
In a simulation study you imitate as many conditions and characteristics as possible of the real thing, in this case the planet you have not visited. By simulating as many conditions as possible you can visualize what the planet might be like and learn things about it without actually visiting it.
Simulation studies cannot be used to learn about a planet we have never visited because we do not know anything about the planet.

What is simulation?

A simulation is a method of simulating a process or change in the actual world to forecast future events or to explain past events and their causes. These days, simulations are frequently carried out using computers. Scientists use simulations to find answers and to test complicated systems.

A fire drill is used in this instance to get everyone ready for an impending event. In fire drills, the fire alarm is sounded even when there isn't actually a fire.

Therefore, the correct option is c.

Hence the expression of ω in terms of m and k is

There is the more role of the moon than the sun to occur tides in the oceans,why?

Answers

Answer:

The ocean tides on earth are caused by both the moon's gravity and the sun's gravity. ... Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.

The moon plays a larger role than the sun in causing tides in the oceans because it is much closer to Earth and has a stronger gravitational pull on our planet. The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them.

Although the sun is much larger than the moon, its gravitational pull on Earth is much weaker because it is much farther away. The moon, on the other hand, is much smaller than the sun, but it is much closer to Earth and exerts a stronger gravitational force on our planet. This gravitational force causes the water in the oceans to bulge towards the moon, causing high tides.

In addition to the gravitational force, the shape of the ocean basins, the rotation of the Earth, and the positions of the sun and moon also play a role in causing tides. However, the moon's gravitational force is the primary factor that causes tides in the oceans.

What unit is used to measure the period of a wave?
A. Seconds
B. Meters
C. Hertz
D. Meters/second

Answers

Answer:

D. Meters/Seconds

Explanation:

The time period of a wave is measured in seconds.

A typical wave involves both time and distance.  Consider a sound wave, which is basically a periodic modulation of the local air pressure.  We "hear" the sound because our ears respond to the variations of pressure.

The most common metric of a sound wave is frequency.  This is the rate at which the change in pressure occurs, and is measured in cycles per second, formally known as "hertz".  The period is the inverse of frequency andl has the units of seconds per cycle, commonly stated simply as seconds.

The plane of a5cm*8cm rectangular loop of wire is parallel to a 0.19T magnetic field the loop carries a current of 6.2 A. What torque acts on aloop? What is the magnetic moment of the loop?

Answers

Answer:

Torque; τ = 4.712 × 10^(-3) J

Magnetic moment; M = 0.0248 J/T

Explanation:

Torque is gotten from the formula;

τ = BIA

Where;

B is magnetic field

I is current

A is area

We are given;

B = 0.19T

I = 6.2A

Rectangle dimensions = 5cm by 8cm = 0.05m by 0.08m

Thus;

Area; A = 0.05m × 0.08m = 0.004 m²

Thus;

τ = 0.19 × 6.2 × 0.004

τ = 4.712 × 10^(-3) J

Formula for the magnetic moment is given by;

M = IA

M = 6.2 × 0.004

M = 0.0248 J/T
