Answers

Answer 1

Answer:

1)So, the mass(m) of the tv is 75kg and the scale(weight)=825 N therefore you devide the weight by the mass which is equal to 11m/s^2

2)First things first you need to know the gravitational force here on earth which is 9.8(approximately 10) I will sove for 9.8 and 10 so you can choose

the fish has a mass of 2.4kg and the gravity= 9.8 so the weight is equal to the mass*gravity= 23.52

now if you use 10 as the gravity= 2.4*10= 24

3) here the weight is 250N and gravity is 9.8(10) so we just devide the weight by the gravity= 250/9.8= 25.51

                         250/10= 25( if gravity is 10)

Answer 2

Answer:

Explanation:

12.since W=mg where m is mass and g which is accelaration due to gravity,

  g=825N/75kg

  g=11 m/s^2

13.W= 2.4kg * 9.81m/s^2

      =23.544kg m/s^2=23.544N

14.m=250N/9.81ms^-2

       =25.48kg

A. The strength of the magnet increased as the amount of current increased.

Explanation:

1. When a voltage is applied to these plates an electrical current flows charging up one plate with a positive charge with respect to the supply voltage and the other plate with an equal and opposite negative charge.

If the capacitors are connected by a conductor they must have equal potentials. If their charges are not +/- Q there will be a potential difference and charges will flow until they are +/- .

2. Based upon the results of the experiment which is graphed, an increase in current increases the number of paperclips picked up. The increase in current produced a stronger magnetic field from the electromagnet created. The ability to pick up paperclips testifies to the strength of the magnet and this strength is because of the current emitted to the coils which in turn magnetizes the nail

What do viruses and living things have in common?

Answers

Answer:

They contain genetic information needed to produce more viruses in the form of DNA or RNA.

Explanation:

Viruses are extremely small infectious agents that invade cells of all types. Once inside another cell, viruses become hijackers, using the cells' machinery to produce more viruses. Whether viruses constitute living organisms or merely conglomerations of molecules has been a source of debate for many years. One of the fundamental hallmarks of life is the ability to reproduce. Whether viruses have this ability is key to a debate over their status as living things. Some argue that since viruses cannot reproduce independently, they are not alive. However, similar to viruses, there are a few prokaryotes that are obligate parasites and cannot reproduce without a host. But these prokaryotes show another hallmark of life that viruses lack: growth. Once assembled, a virus does not change in size or chemical composition. They lack the machinery for producing energy to drive such biological processes. This makes them radically different from any known organism. Viruses do, however, show some characteristics of living things. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA. They evolve to adapt to their hosts. So while it is doubtful viruses are truly alive, they are clearly very similar to living organisms. There is more diversity among viruses than among all groups of living organisms combined. New varieties are constantly being described. It would be nearly impossible to describe all of the groups of viruses and their characteristics briefly. Instead, we will look at the characteristics shared by all viruses, such as their basic structure and general replicative cycle. Then we will discuss the features used to classify new viruses, such as shape and form of genetic material.

Answer:

cell-based life.

Explanation:

Still, viruses have some important features in common with cell-based life. For instance, they have nucleic acid genomes based on the same genetic code that's used in your cells (and the cells of all living creatures). Also, like cell-based life, viruses have genetic variation and can evolve

Explanation:

A) Glacier causes erosion by abrasion and plucking.  

B) The sediment deposited by glaciers is called a moraine.

C) When a chunk of ice remained behind by a receding glacier melts, the water stays in the kettle, forming a kettle lake.

What are abrasion, plucking, and moraine?

Abrasion contains the wear, polishing, and scratching produced in the bedrock by the thicker rock fragments brought by the ice, and in that way, grooves are formed.

Plucking generally takes place when advancing ice will push against fractured bedrock. Additional breaks can produce stress, while warmer temperatures and friction from glacier movement can bring the melting.

Moraine is the deposit of trawls of material fragmented by glaciers, which create mountain ranges because of their accumulation.

Glaciers are contacted by ice deposits due to continental glaciation. These forms develop with the glacier outwash and leave ice deposits. It generates a kettle lake when a large chunk of ice left a depression in the glacial drift when the ice melts a kettle-like hole is formed.

A student walks a distance of 3 km in 20 minutes calculate his average speed

Answers

Answer:

His average speed is 0.15 kilometer per minute or 2.5 meters per second.

Explanation:

average speed = distance/time

x = 3 km/20 minutes

x = 0.15

x = 3000 m/1200 s

x = 2.5

If a  student walks a distance of 3 km in 20 minutes then the average speed of the student would be 9 kilometers per hour.

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.

As given in the problem we have to calculate the average speed of the student if a  student walks a distance of 3 km in 20 minutes.

The distance traveled in 20 min = 3 kilometers

The distance traveled in 60 min = 3 × 3

                                                      = 9 kilometers

Thus, If a  student walks a distance of 3 km in 20 minutes then the average speed of the student would be 9 kilometers per hour.

a bubble of air of volume 1cm^3 is released by a deep sea diver at a depth where the pressure is 4.0 atmospheres. assuming its temperature remains constant (T1=T2), what is its volume just before it reaches the surface where the pressure is 1.0 atmosphere?

Answers

Answer:

hope this helps!

Explanation:

Volume of the air bubble, V1=1.0cm3=1.0×10−6m3

Bubble rises to height, d=40m

Temperature at a depth of 40 m, T1=12oC=285K

Temperature at the surface of the lake, T2=35oC=308K

The pressure on the surface of the lake: P2=1atm=1×1.103×105Pa 

The pressure at the depth of 40 m: P1=1atm+dρg

Where,

ρ is the density of water =103kg/m3

g is the acceleration due to gravity =9.8m/s2

∴P1=1.103×105+40×103×9.8=493300Pa

Where, V2 is the volume of the air bubble when it reaches the surface.

A force refers to that which produces or opposes motion. When force(s) is/are acting on a body, they either cause motion to occur or prevent motion from occurring. An example of a force which opposes motion is friction.

For a car being pushed along a driveway, the two possible horizontal forces that act on it are push which moves it forward and friction which resists its motion.

b. Calculate the potential energy, the kinetic energy, and the total energy of the car as it leaves the cliff.

c. Make a graph displaying the kinetic, gravitational potential, and total energy of the car at each 10 m

Explanation:

The potential energy of the car at that position is 10.6 x 10⁵ J.

What is meant by potential energy ?

Potential energy of an object is defined as the energy acquired by the object by virtue its position.

Here,

Mass of the car, m = 1200 kg

Speed of the car, v = 29 m/s

Height of the cliff, h = 90 m

Therefore,

Potential energy of the car, PE = mgh

PE = 1200 x 9.8 x 90

PE = 10.6 x 10⁵ J

Hence,

The potential energy of the car at that position is 10.6 x 10⁵ J.

A 30.6 kg crate initially at rest on a horizontal floor requires a 100 N 30° with the horizontal force to set it in motion. Find the coefficient of static friction between the crate and the floor

Answers

The frictional force opposes the forward motion of the crate. The coefficient of static friction is 0.2.

Using the formula;

Fa = - Ff + mgsinθ

but Ff = μsFN and N = mgcosθ

Hence;

Fa = mgsinθ - μsmgcosθ

μsmgcosθ = mgsinθ - Fa

μk =  mgsinθ - Fa/mgcosθ

μk =  coefficient of static friction = ?

Fa = horizontal force = 100N

m = mass = 30.6 kg

θ = angle = 30°

g = acceleration due to gravity = 10 m/s^2

Substituting values;

μk =  [(30.6 × 10) sin 30°] - 100 / (30.6 kg × 10) cos 30°

μk = 153 - 100/265
