Which has greater density- 1 kg of water or 10kg of water?

Answers

Answer:

I believe that it will be 10kg of water

Explanation:

Because a measure of the amount of information on a storage medium (tape or disk). For magnetic tape it is the amount of information recorded per unit length of tape (bits per inch or millimeter); for a disk, a fixed number of bits per sector, sectors per track, and tracks per disk.

The density in both the case will be equal, just the difference will be in the volume they occupy.

What is density?

In practice, density is the weight of a substance per unit volume. Water has a density of about 1 gram per milliliter, but this varies depending on temperature and whether or not substances are dissolved in it. Because ice is less dense than liquid water, it floats in your glass.

This allows many aquatic organisms to survive the winter. If ice were more dense than water, it would continue to freeze and sink until the entire lake was frozen.

Any amount of water has the same density. Whereas one gram of water has a volume of one milliliter, ten grams have a volume of ten milliliters.

Thus, the density will be same.

A 780 kg vehicle accelerates at 4 m/s2. How much force is the car generating?

Answers

Explanation:

Given

mass (m) = 780 kg

acceleration (a) = 4 m/s²

Force (F) = ?

We know

F = m * a

= 780 * 4

= 3120 Newton

The car is generating 3120 Newton force.

Answers

Answer:

metal because A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. Thermal insulators like plastic and wood don't transfer heat as easily.

Which magnets need electric current for magnetism?
a. Bar magnets b. Temporary magnets c. Permanent magnets magnets

Answers

Probably temporary magnets, but I’m. It sure

Temporary magnets require electric current to produce magnetism and magnetic field lines B) Temporary magnets

In electromagnets, their magnetism is dependent on electricity  with an iron core in the center. If we add an iron core to a solenoid, we can increase its magnetic field strength . When we connect  a battery to a solenoid and wrap the sanded copper wire around a nail, a magnetic field is created. This force is generated by the magnetic field that's  created when current flows through the coil.

As long as there is a direct current running  through the coil, the nail will retain its magnetic properties. However, once the current stops, the magnetism of the nail is lost .  Creating electromagnets can be achieved by winding wire around the iron core.

The advantages of electromagnets are :

Electromagnets can be turned on and off magnetic Fields can be increased and decreased Electromagnets can be cheap compared to permanent magnets. The same cannot be said for a permanent magnet.

What happens as a bungee jumper gets closer to Earth's surface?
A. Gravity decreases
B. His mass increases
C. Air resistance decreases
D. His velocity increases

Answers

Answer:

Velocity increases

Explanation:

Gravity is constant, except when discussing "apparent weight"

Mass is constant here

Air resistance would actually increase

Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.

A contract between a manufacturer and a consumer of light bulbs specifies that the mean lifetime of the bulbs must be at least 1000 hours. As part of the quality assurance program, the manufacturer will institute an inspection program for each day's production of 10,000 units. An ordinary testing procedure is difficult since 1000 hours is over 41 days! Since the lifetime of a bulb decreases as the voltage applied increases, a common procedure is to perform an accelerated lifetime test in which the bulbs are lit using 400 volts (compared to the usual 110 volts). At such a voltage, a 1000-hour bulb is expected to last only 3 hours. This is a well-known procedure, and both sides have agreed that the results from the accelerated test will be a valid indicator of lifetime of the bulb.The manufacturer will test the hypotheses H0 : = 3 versus Ha: < 3 at the = 0.01 significance level with a simple random sample of 100 bulbs.a.
