Force required to accelerate 10 kg object to 5.9 m/s/s ?

Mass = 10 kg

Acceleration = 5.9 m/s^2

Force = Mass * Acceleration

Force = 10 kg * 5.9 m/s^2

Force = 59 kg m /s^2 = 59 N

Answer:

[tex]t = \sqrt{\frac{s}{a} }[/tex]

Explanation:

In order to find the time in a uniform magnetic field in terms of acceleration and time we will use the general formula of acceleration, which is given as follows:

[tex]a = \frac{v}{t} \\\\where,\\\\a = acceleration\\v = velcoity = \frac{s}{t} \\\\t = time\ taken\\s = distance\ covered\ in\ the\ field\\\\therefore,\\\\a = \frac{s}{t^2}\\\\t^2 = \frac{s}{a}\\\\t = \sqrt{\frac{s}{a} }[/tex]

This formula can be used to measure time in a uniform electric field in terms of distance and time only.

Answer:

its warmer than outside in winter and its colder than outside in summer

Explanation:

The perception of warmth or coolness is relative to the temperature difference between the body and the environment. Even though the temperature inside the room remains constant year-round, the relative temperature difference between the environment outside and the room can cause a subjective sensation of warmth or coolness.

Temperature is a physical quantity that measures the degree of hotness or coldness of a body or a substance. It is a scalar quantity, which means it has only a magnitude and no direction.

The SI unit of temperature is the Kelvin (K), but the temperature is commonly measured in degrees Celsius (°C) or degrees Fahrenheit (°F) as well.

The temperature difference is the numerical value of the difference between the temperatures of two objects or substances. It represents the amount of heat that flows from one object to another due to the temperature gradient between them. The temperature difference is also a scalar quantity, and its unit is usually expressed in degrees Celsius or Kelvin.

The temperature difference is important in many areas of science and engineering, including thermodynamics, heat transfer, and meteorology. It is also used to measure the efficiency of heating and cooling systems, such as air conditioners and refrigerators.

Here in this question,

This phenomenon occurs due to the relative difference in temperature between the environment outside and the temperature inside the room. The feeling of warmth or coolness is a subjective sensation that depends not only on the actual temperature but also on the difference in temperature between the person's body and their surroundings.

During the winter, the temperature outside is generally colder than the temperature inside the room which is kept at a constant temperature. When a person comes into the room from the cold outside, their body temperature is lower than the room temperature, so they feel warmer inside the room. This is because the heat from the warm room transfers to the person's body, raising their body temperature and making them feel warmer.

On the other hand, during the summer, the temperature outside is usually warmer than the temperature inside the room. When a person comes into the room from the hot outside, their body temperature is higher than the room temperature, so they feel cooler inside the room. This is because the heat from the person's body transfers to the cooler room, lowering their body temperature and making them feel cooler.

Therefore, the relative temperature difference between the environment outside and the room can cause a subjective sensation of warmth or coolness.

Answer:

1 =1 +1

f. v u

Explanation:

f is the focal length

v is the image distance

u is the object distance

1/f = 1/v + 1/u

The above formula gives us the relation between 'f' 'v' & 'u', Where :

              f = focal length

              v = image distance

              u = object distance

This formula not only used for concave mirror, but also for convex mirror.

Answer:

when current passes through a wire amagnetic field is created.

Whenever the current passes through a wire then the magnetic fields in the form of a circular loop form around the wire.

The magnetic field is generally a force that is generated due to the flow of electrons in the wire.

The magnetic field generated is always in the circular loop around the wire.

The magnetic field only remains around the wire as far there is the flow of the current in the wire.

if the flow of the current terminated then the force of the magnetic field also vanished.

Thus Whenever the current passes through a wire then the magnetic fields in the form of a circular loop form around the wire.

Answer:

Say a 14 year old girl was at a construction site and she was asked to move something like a 10,000 pound brick( one brick). She would be acting on it as the unbalanced force but they would still not change their position.

so to say the girl would be doing everything she could to move that brick but the brick would still be in that same spot so the unbalanced force (the girl) would be acting on the thing that was at rest but it wouldn't move.

so the unbalanced force would not really be acting on the thing at rest; even though the unbalanced force was doing something to the brick.

Answer:

a) The distance after 1 minute will be x = 600 m.

b) The distance of vertical drop from A to B is  [tex]\Delta y=17658\: m[/tex].

Explanation:

Let's use the parabolic motion equations. Here we have a horizontal initial velocity, and knowing that the horizontal velocity is a constant we have:

a)

[tex]v_{x}=\frac{\Delta x}{\Delta t}[/tex]    (1)

Where:

Usinf (1) we find Δx:

[tex]\Delta x=v_{x}\Delta t[/tex]    

[tex]\Delta x=10*60=600 m[/tex]      

Therefore, the distance after 1 minute will be x = 600 m

b)

Here we need to find Δy = y(A)-y(B), this is the distance of vertical drop from A to B.

Using the following equation we will get it:

[tex]y_{B}=y_{A}+v_{iy}t-\frac{1}{2}gt^{2}[/tex]

Let's recall that the initial velocity in the y-direction is 0.

[tex]y_{A}-y_{B}=0t+\frac{1}{2}gt^{2}[/tex]

[tex]\Delta y=\frac{1}{2}gt^{2}[/tex]

[tex]\Delta y=\frac{1}{2}(9.81)(60)^{2}[/tex]  

[tex]\Delta y=17658\: m[/tex]  

Therefore, the distance of vertical drop from A to B is  [tex]\Delta y=17658\: m[/tex].

Answer:

1.91 × 10⁸ m/s

Explanation:

[tex]n = \frac{c}{v} \\ 1.57 = \frac{3.0 \times {10}^{8} }{v} \\ v = 1.91 \times {10}^{8} \: ms {}^{ - 1} [/tex]

The speed of light in a medium if the index of refraction is 1.57 is 1.91 * 10⁸ m/s

The refractive index of a material is the ratio of speed of light in air to speed of light in the medium. It is given by:

Refractive index(n) = speed of light in air(c) / speed of light in material(v)

Given that n = 1.57, c = 3 * 10⁸ m/s, hence:

n = c/v

1.57 = 3 * 10⁸ / v

v = 1.91 * 10⁸ m/s

The speed of light in a medium if the index of refraction is 1.57 is 1.91 * 10⁸ m/s
