Which image shows an example of the strong nuclear force in action?

Answer:

False

Explanation:

Neither the USGS nor any other scientists have ever predicted a major earthquake. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.

Answer: No , a chemical change has not occured as it was easily reversed.

Explanation:

Chemical change is defined as a change in which rearrangement of atoms take place and leads to formation of new substances. It can only be reversed with the help of a chemical reaction.

Physical change is defined as a change which leads to change in shape, size or state of the substance changes. No new substance is formed.It can be easily reversed.

As the hair colour was washed out and returned to its original brown colour, it was a physical change.

Answer:

Velocity

Explanation:

Answer:

The options are not given, so i will answer in a really general case.

There are two equations that describe how mass affects the motion of an object.

The most generical one, Newton's second equation of motion.

This says that:

F = m*a

Force equals mass times acceleration.

Remember that acceleration tells us how the motion of an object changes as time passes.

So if we isolate the acceleration we get:

a = F/m

Here you can see that the mass is in the denominator, so, for a fixed force F, if we increase the mass of the object, the acceleration will decrease, which means that as more mass has an object, "harder" is to accelerate it.

Now from an energy point of view.

The kinetic energy (the motion energy of a moving object) is written as:

T = (1/2)*m*(v^2)

where:

m = mass

v = velocity.

Here, for a fixed velocity v, if we increase the mass, we also increase the kinetic energy.

This means that if we have two objects, one with a small mass m, and the other with a larger mass M, and we want to give both objects the same velocity v, we will need more energy for the object with more mass.

So in general we can conclude that mass "opposes" to the motion.

Now, we also can define the term "testable"

A hypothesis is testable if we can think of an experiment to test it, if there is no experiment, then the hypothesis is not testable.

Cell theory states that all living things contain at least one cell, and there are certainly more types of living things than simply plants and animals. For example bacteria and fungi.

So your answer would be A.

Answer: C

Explanation:

all the other ones are part of the cell theory

Answer:

The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

~Brainiliest?~

Answer:

We describe motion in terms of velocity and acceleration. Velocity: The rate of change of displacement of an object (displacement over elapsed time) is velocity. Velocity is a vector since it has both magnitude (called speed) and direction. ... Acceleration: The rate of change of velocity is acceleration.

Explanation:

Displacement is a vector which points from the initial position of an object to its final position. ... Instantaneous velocity, on the other hand, describes the motion of a body at one particular moment in time. Acceleration is a vector which shows the direction and magnitude of changes in velocity.

Displacement is the vector difference between the ending and starting positions of an object. Velocity is the rate at which displacement changes with time. ... The average velocity over some interval is the total displacement during that interval, divided by the time.

Answer: It leads to a front. A front is.., I don't know how to explain it, so I'll add a picture. Fronts are made out of clouds and usually bring rain. So the answer is C: The formation of clouds and rain.

Explanation:

When you get out of bed in a morning it's most likely too be cold so your bare feet on a floor not carpet a bare floor will feel cold since the temperature and molecules had changed and if you step on a warm fuzzy rug it will feel warm since your feet are cold and the rugs fuzziness or material keeps you warn

We feel more cold on feet on morning because heat from our feet will flow to the cold floor. We feel more cold on the bare floor than the rug since it conducts heat away from our feet.

Heat will be transfer on a temperature gradient from one substance to the other.  Heat is transferring from the hot body to the colder body. There are three types of heat transfer are there namely, conduction, convection and radiation.

Conduction is the heat transfer in solids , convection in liquids and radiation is the heat or energy transfer mode in gases and vacuum.  At the morning, the floor will be more cool whereas our body will be hotter, thus heat will flow our body to floor make our feet cool.

A bare floor will conduct thermally more than a rug do. Thus the bare floor conducts heat away from our feet and make our feet more cool.

Hello your question is incomplete below is the missing piece

What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.

answer :  25.73 m/s

Explanation:

Given

V1 = 15 miles/hour =  6.71 m/s [ 45° EN ]

V2 = 18 m/s [ 5° NE ]

Calculate  the resultant velocity

Vr = 6.71 m/s[45°] + 18m/s[5°].

Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )

Vr = ( 4.74  + 4.74 i  )+  ( 17.93 + 1.57i) = 22.67 + 12.18i.

Therefore the magnitude

= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

Answer:

The movement of a roller coaster is accomplished by the conversion of potential energy to kinetic energy. The roller coaster cars gain potential energy as they are pulled to the top of the first hill. As the cars descend the potential energy is converted to kinetic energy. Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy.

Answer:

The electrical energy consumed in boiling the water is 0.0788 kWh

Explanation:

Given;

mass of the water, m = 600 g = 0.6 kg

power rating of the kettle, P = 1500 W = 1.5 kW

specific heat capacity of water, c = 4,200 J/kg⁰C

density of water, = 1000 kg/m³

time taken to boil the water, t = 3 mins + 9 s = (3 x 60s) + 9 s = 180 s + 9 s = 189 s = [tex]189 \ s \times \frac{1 hr}{3.600 \ s} = 0.0525 \ hr[/tex]

The electrical energy consumed in boiling the water is calculated as;

E = P x t

E = 1.5 kW  x 0.0525 hr

E = 0.0788 kWh

Therefore, the electrical energy consumed in boiling the water is 0.0788 kWh

Answer:

The correct answer is: 0°C + 0°C = 32°F

Explanation:

We need to remember the conversion equation from Celsius to Fahrenheit:

[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]

In our case x = 0, then y will be:

[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]

[tex]y=32^{\circ}F[/tex]

Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.

Then, knowing that 0°C = 32°F we can conclude that:

[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

Answer:

a change of position in relation to another object.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

Hence, motion is a change of position in relation to another object.

The more lines, the greater the charge.

Answer:

21.5 miles

Explanation:

Distance = Speed * time

Distance  traveled in first 6 minutes = 52 * [tex]\frac{6}{60}[/tex]  = 5.2 miles

Distance  traveled in next 3  minutes = 46 *[tex]\frac{3}{60}[/tex] = 2.3 miles

Remaining minutes = 30 - 6 -3 = 21 minutes

Distance  traveled in 21 minutes = 40 * [tex]\frac{21}{60}[/tex] = 14 miles

Total distance traveled = 5.2 + 2.3 + 14 = 21.5 miles
