Answer:

not enough

Explanation:

information given

Answer:

Sample Response: In the lab, I discovered the air pressure, air temperature, and relative humidity conditions that create snow, rain, thunderstorms, fog, and clear skies. I learned that low-pressure areas usually experience snowy, rainy, and stormy weather, and that high-pressure areas usually experience either foggy or sunny weather. Knowing how these atmospheric conditions influence weather help weather forecasters predict weather patterns through maps and other information.

Answer:

[tex]124.62\ \text{rad/s}[/tex]

[tex]3.71\ \text{m/s}[/tex]

[tex]1.23\ \text{km/s}^2[/tex]

[tex]20.28\ \text{m}[/tex]

Explanation:

r = Radius of disk = 7.9 cm

N = Number of revolution per minute = 1190 rev/minute

Angular speed is given by

[tex]\omega=N\dfrac{2\pi}{60}\\\Rightarrow \omega=1190\times \dfrac{2\pi}{60}\\\Rightarrow \omega=124.62\ \text{rad/s}[/tex]

The angular speed is [tex]124.62\ \text{rad/s}[/tex]

r = 2.98 cm

Tangential speed is given by

[tex]v=r\omega\\\Rightarrow v=2.98\times 10^{-2}\times 124.62\\\Rightarrow v=3.71\ \text{m/s}[/tex]

Tangential speed at the required point is [tex]3.71\ \text{m/s}[/tex]

Radial acceleration is given by

[tex]a=\omega^2r\\\Rightarrow a=124.62^2\times 7.9\times 10^{-2}\\\Rightarrow a=1226.88\approx 1.23\ \text{km/s}^2[/tex]

The radial acceleration is [tex]1.23\ \text{km/s}^2[/tex].

t = Time = 2.06 s

Distance traveled is given by

[tex]d=vt\\\Rightarrow d=\omega rt\\\Rightarrow d=124.62\times 7.9\times 10^{-2}\times 2.06\\\Rightarrow d=20.28\ \text{m}[/tex]

The total distance a point on the rim moves in the required time is [tex]20.28\ \text{m}[/tex].

Answer:

If all these three charges are positive with a magnitude of [tex]1.8 \times 10^{-8}\; \rm C[/tex] each, the electric potential at the midpoint of segment [tex]\rm AB[/tex] would be approximately [tex]8.3 \times 10^{3}\; \rm V[/tex].

Explanation:

Convert the unit of the length of each side of this triangle to meters: [tex]10\; \rm cm = 0.10\; \rm m[/tex].

Distance between the midpoint of [tex]\rm AB[/tex] and each of the three charges:

Let [tex]k[/tex] denote Coulomb's constant ([tex]k \approx 8.99 \times 10^{9}\; \rm N \cdot m^{2} \cdot C^{-2}[/tex].)

Electric potential due to the charge at [tex]\rm A[/tex]: [tex]\displaystyle \frac{k\, q}{d({\rm A})}[/tex].

Electric potential due to the charge at [tex]\rm B[/tex]: [tex]\displaystyle \frac{k\, q}{d({\rm B})}[/tex].

Electric potential due to the charge at [tex]\rm A[/tex]: [tex]\displaystyle \frac{k\, q}{d({\rm C})}[/tex].

While forces are vectors, electric potentials are scalars. When more than one electric fields are superposed over one another, the resultant electric potential at some point would be the scalar sum of the electric potential at that position due to each of these fields.

Hence, the electric field at the midpoint of [tex]\rm AB[/tex] due to all these three charges  would be:

[tex]\begin{aligned}& \frac{k\, q}{d({\rm A})} + \frac{k\, q}{d({\rm B})} + \frac{k\, q}{d({\rm C})} \\ &= k\, \left(\frac{q}{d({\rm A})} + \frac{q}{d({\rm B})} + \frac{q}{d({\rm C})}\right) \\ &\approx 8.99 \times 10^{9}\; \rm N \cdot m^{2} \cdot C^{-2} \\ & \quad \quad \times \left(\frac{1.8 \times 10^{-8} \; \rm C}{0.050\; \rm m} + \frac{1.8 \times 10^{-8} \; \rm C}{0.050\; \rm m} + \frac{1.8 \times 10^{-8} \; \rm C}{\sqrt{3} \times (0.050\; \rm m)}\right) \\ &\approx 8.3 \times 10^{3}\; \rm V\end{aligned}[/tex].

Answer:

the force of attraction between the two charges is 3.55 N.

Explanation:

Given;

first charge carried by the object, q₁ = 15.5 µC

second charge carried by the q₂ = -7.25 µC

distance between the two charges, r = 0.525 m

The force of attraction between the two charges is calculated as;

[tex]F = \frac{kq_1q_2}{r^2} \\\\F = \frac{(9\times 10^9)(15\times 10^{-6})(7.25\times 10^{-6})}{(0.525)^2} \\\\F = 3.55 \ N[/tex]

Therefore, the force of attraction between the two charges is 3.55 N.

Answer:

Explanation:

Since it lateral acceleration is is its centripetal acceleration, the centripetal acceleration, a is given by

a = v²/r where v = speed of Dodge Viper GTS= 86.5 km/h = 86.5 × 1000 m/3600 s = 24.03 m/s and r = radius of skid pad = 61.0 m.

So, a = v²/r

= 24.028 m/s ÷ 61.0 m

= 0.394 m/s²

So, its maximum lateral acceleration is 0.394 m/s². Since g = acceleration due to gravity = 9.8 m/s²

a/g = 0.394 m/s² ÷ 9.8 m/s² = 0.04

So, a = 0.0402g

a ≅ 0.04g

The desert biome is an ecosystem that forms due to the low level of rainfall it receives each year. Deserts cover about 20% of the Earth. There are four major types of desert in this biome - hot and dry, semiarid, coastal, and cold. They are all able to inhabit plant and animal life that are able to survive there. Although the daytime temperatures of the desert biome are very hot, they can get very cold at night. The Sahara Desert is the largest desert in the desert biome. It covers over 300 million square miles.

Answer:D. Watching the left-over dirt from a comet burn up by friction as the pieces hit the Earth's atmosphere

Explanation: A meteor shower is giant rocks moving across the sky

There must be an invitation for d. watching the left-over dirt from a comet burn up by friction as the pieces hit the Earth's atmosphere

Meteor showers occur when dust or particles from asteroids or comets enter Earth's atmosphere at very high speed. When they hit the atmosphere, meteors rub against air particles and create friction, heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars

hence correct option will be D) Watching the left-over dirt from a comet burn up by friction as the pieces hit the Earth's atmosphere

Answer:

No, he hasn't done any work.

Explanation:

In this scenario, the weightlifter hasn't done any work because even though he lifted the bell for a specific period of time, he didn't cover any distance.

Mathematically, work done is given by the formula;

Work done = force * distance

[tex] W = F * d[/tex]

Where,

W is the work done

F represents the force acting on a body.

d represents the distance covered by the body.

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

[tex] Power = \frac {Energy}{time} [/tex]

Explanation:

Answer:

athlete  W = 2560 J

roce      W_{fr} = - 2560 J

Explanation:

For this exercise we can use the relationship between work and kinetic energy

          W = ΔK

          W = K_f -K₀

as the bearing of rest its v₀ = 0 and the final velocity is v = 8 m / s

athlete's job is

           W = ½ m [tex]v_{f}^2[/tex] - 0

let's calculate

           W = ½ 80 8²

            W = 2560 J

For the work of the friction force let us use that since the athlete goes at constant speed, they relate it to zero, therefore the forces are in equilibrium

             ∑F = 0

             F- fr = 0

             F = fr

Therefore, the magnitude of the friction force is equal to the force applied by the athlete, as the friction force always has the opposite direction to the movement, its work is

             W_{fr} = - W_{atlete}

             W_{fr} = - 2560 J

When a large number of magnetic domains are aligned, a strong magnet produces more magnetic attraction compared to a weak magnet and non-magnetic material.

Magnetic induction occurs when a magnetic field is used to magnetize another object.

This process occurs when the magnetic domains are aligned in the same direction, which causes the object become magnetized in that direction, thereby forming a magnet.

Thus, when a large number of magnetic domains are aligned, a strong magnet produces more magnetic attraction compared to a weak magnet and non-magnetic material.
