Determine the change in velocity between 2.0 to 6.0 seconds. ____

Group of answer choices

-1.6 m/s

-2.1 m/s

-9.5 m/s

Explanation:

Gravity

Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).

Answer:

volume of cheese=l×b×h=5×6×4=120cm³

density=mass/volume=(467/120)=3.89g/m³

Answer:

15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2

Explanation:

Work = 196 J = 196 kg.m^2.s^-2

[We know that 1J = 1 kg.m^2.s^-2]

Displacement = 2m

Acceleration (g) = 9.8ms^-2

We know that,

W=Fs and F=ma

So, W = (ma)s

=> W = m×a×s

=> 196 kg.m^2.s^-2 = m×9.8ms^-2×2m

=> 196 kg.m^2.s^-2 = m×19.6m^2.s^-2

=> 196 kg.m^2.s^-2 = m×19.6m^2.s^-2

=> (196 kg.m^2.s^-2)/(19.6m^2.s^-2) = m

=> 10kg = m

So, mass = 10kg

Answer:

He traveled 9km

Explanation:

To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km

Explanation:

momentum = mv

m = 8 kg

v = 12 m/s

momentum = 8 * 12 = 96 kg m/s

Answer:

C. 2 and 4

Explanation:

my teacher went over it and the answer was that

The sections of the track in which the sled would experience an unbalanced force are: C. Sections 2 and 4.

In Science, there are two (2) main types of force that acts on an object and these include:

An unbalanced force refers to a type of force that occurs when two (2) or more forces acting on an object are unequal in magnitude, and as such, it typically results in a change of motion.

In this scenario, the sections of the track in which the sled would experience an unbalanced force are sections 2 and 4 respectively.

Answer:

Power = 1471000[W]

Explanation:

In order to solve this problem, we must use the conversion factor of horsepower to Watts.

1 [Hp] → 735.5 [W]

Now using the conversion factor:

[tex]2000[Hp]*\frac{735.5W}{1Hp}=1471000[W][/tex]

Answer:

A: High Frequency Wave Wave B: Low Frequency Wave Wave

Explanation:

The high-frequency waves are those that have a range of 3 to 30 MHz and have a longer wavelength that has more energy than a low-frequency wave and the more closer are the crest of the waves the more is frequency.

Low-frequency ranges from 30 to 300 kHz and ranges from 10 to 1 km and is suitable for long-distance communication. Mainly used in aircraft navigation and weather systems.

Answer:

A

Explanation:

Answer:

Product

Explanation:

The force between two charges is given by :

[tex]F=\dfrac{kq_1q_2}{r^2}[/tex] ...(1)

Where

k is electrostatic constant

q₁ and q₂ are charges

r is the distance between charges

From equation (1), it is clear that the magnitude of the force is directly proportional to the product of charges.

Answer:

Newton

Explanation:

The unit of force is Newton and it is given after Sir Isaac Newton for his tremendous works in this regard.

 Force is the product of mass and acceleration of a body.

    Force  = mass x acceleration  

 The unit of mass = kg

                    acceleration  = m/s²

So;

      1N  = 1kgm/s²

Therefore, the unit of force is newtons and 1N is equal to  1kgm/s²

Answer:

m = 0.51[kg]

Explanation:

Potential energy is defined as the product of mass by gravity by height.

[tex]E_{pot}=m*g*h[/tex]

where:

Epot = potential energy = 15 [J]

m = mass [kg]

g = gravity acceleration = 9.8 [m/s²]

h = elevation = 3 [m]

Now replacing:

[tex]E_{pot}=m*g*h\\15=m*9.8*3\\m = 0.51[kg][/tex]

Answer:

5

Explanation:

Because it right

Answer:

stove

Explanation:

The stove is the independent variable in this question as it does not depend on anything like other variables such as pot, water, temperature and of cause pasta.

The pot depends on the stove, the water depends on the pot and stove, the pasta depends on the water and its temperature.

Cheers.
