Answer 1
A plan Murrow produces a virtual image
Answer 2

Answer:

Explanation:

A plane mirror is the kind you look into when you look into a "regular" mirror. The image you see is right-side-up. These images are virtual. Real images are always upside down and are made by mirrors that are "parabolic" in shape. Virtual images are always right-side-up.

Answer:

Explanation:

From physics, which is directly related to math (especially when it comes to parabolic motion!), we learn that at the very top of the parabola the object has to stop for a millisecond so it can turn around and fall back to earth. This translates to a velocity of 0 at its highest point. So B.

1. explain the procedure undertaken if you have to measure the density of the contents of a milk carton. 2. two objects have the same mass. How about the density of the two objects?​

Answers

To calculate the density of a substance, its mass and volume has to be determined. So that:

i. For the milk in the carton, its mass and volume should be known.

ii. For the two objects given in the question, their individual masses and volumes have to be determined.

Density of a substance (ρ) is the rate of the mass (m) of the substance to its volume (V). It is measure in kg/[tex]m^{3}[/tex].

i.e ρ = [tex]\frac{m}{V}[/tex]

The density of a substance can be determined once the mass and its volume have been accurately measured.

1. How to measure the density of the contents of a milk carton.

a. Determine the mass of the milk carton with its content.

b. Determine the mass of the milk carton when empty.

c. Subtract the mass of the milk carton when empty from the mass of the carton with its content. This will give the mass of the milk in the carton.

d. Using a beaker, measure the volume of the milk.

e. Divide the mass of the milk by its volume to determine its density.

2. How to measure the densities of two objects of equal mass.

a. Fill an Eureka's can or a beaker with sprout with water to its brim.

b. Slowly drop the mass into the beaker with water so as to collect the volume of the liquid displaced into another beaker.

c. The volume of the liquid displaced is the volume of the mass.

d. Divide the mass of the object by its volume to determine its density.

NB: These procedures are observed to determine the densities of the two object individually.

What is the average speed shown on the graph between point A and point D?

Answers

Answer:

5/3 m/s or

6 km/h

Explanation:

really ? the average speed is just the straight connection in the graph from A to D.

that means the travel time was 40-10 seconds = 30 seconds.

and the distance traveled was 60-10 = 50 meters.

so, the average speed was

50 meters / 30 seconds

to bring this to standard m/s

5 m / 3 s = 5/3 m/s

or to standard km/h

an hour has 60 minutes or 120 30-seconds intervals

50 m/ 30 s × 120/120 = 6000 m / h = 6 km/h

The direction of applied force has to be .............. to the distance in order to say work is done​

Answers

Answer:

Parallel

Explanation:

The work done is defined as the force applied on an object and the displacement in the position of the object in the direction of force.

W = F s cos A

where, F is the force, s is the displacement and A is the angle between force and displacement.

When the angle between the force and the displacement is 90 degree, the work done is zero.

To get the maximum work the angle between the force and the displacement is 0 degree.

So, to get the work done by the force the angle between the force and displacement is 0 degree that means the force and displacement is parallel to each other.

What is the relation between the weight of a body and acceleraton due to gravity?​

Answers

Answer:

All objects on Earth, regardless of their mass, accelerate due to gravity at the same rate - that is, 9.8 m/sec2. The weight of an object can be calculated using the formula for force - F = m * a - where F equals the weight of the object and now the acceleration (a) is the acceleration of gravity (g).

why audiotape, credit cards and videotape not placed closed to a strong magnet

Answers

Answer:

There are many possible causes of magnetic defects in credit cards. But there are two direct causes: 1. Close to a strong magnet 2. Damage from scratches or wear Even if used properly it can cause magnetic defects. But if used incorrectly, it can cause an immediate relapse. If you have never used a credit card due to magnetic defects, check what will cause magnetic defects and for example credit cardMagnetic stripe cards, such as credit cards and cash cards, are more likely to cause magnetic field defects if brought near magnetically generating objects such as magnets. Although exposure to strong magnets does not necessarily lead to failure. However, it should be kept away from objects that may cause magnetic field defects.

Explanation:

Magnetic fields can erase or distort the data stored on these items. The correct option is A.

Magnetic media are used to store information in a magnetic format on audiotapes, credit cards, and videotapes. They may have their magnetic patterns and particle alignment disturbed if they are placed close to a powerful magnet.

The stored data may be lost or damaged as a result. For instance, credit cards' magnetic stripes may become illegible, audiotapes may lose their sound quality or possibly be completely erased, and videotapes may have distorted or scrambled imagery and audio.

To preserve the accuracy and utility of the data they contain, it is crucial to keep these things away from strong magnetic fields.

Thus, the correct option is A.

Non-ideal behavior for a gas is most likely to be observed under conditions of a) high pressure and low temperature. b) high temperature and high pressure. c) high temperature and low pressure. d) standard temperature and pressure. e) low temperature and low pressure.

Answers

Answer:

high temperature and low pressure

Explanation:

Real gases have intermolecular forces of attraction between them hence they can be liquified. However, gases approach ideal behavior at high temperature and low pressure.

According to the kinetic theory of gases, gases molecules move at incredibly high speeds and exhibit no intermolecular interaction because the gas molecules are isolated from each other.

At high temperature and low pressure, gas molecules are found to possess maximum kinetic energy. They move with a very high velocity and have minimal intermolecular interaction between them in accordance with the proposition of the kinetic theory of gases.
