What is the difference between electric field and electrostatic field?

Answers

Answer 1

Answer: Semantically? An electric field does not have to be static while in electrostatics it's generally assumed that the electric field does not change or only changes so slowly that its rate of change doesn't matter. That's very different in electrodynamics where electric and magnetic field changes are always coupled.

Answer 2

Answer: The main difference is that Electrostatic field is because of a stationary charge. And Induced field is because of a changing magneticfield. Since magnetic field and electric field are the same thing in different frames of reference.

In the winter activity of tubing, riders slide down snow covered slopes while sitting on large inflated rubber tubes. To get to the top of the slope, a rider and his tube, with a total mass of 80 kg, are pulled at a constant speed by a tow rope that maintains a constant tension of 360 N. How much thermal energy is created in the slope and the tube during the ascent of a 30-m-high, 120-m-long slope?

Gravitational pull must be measured in units of

Answers

Gravitational force must be measured in units of : meters per second squaredIn every Physics equation, usually the amount of Gravitational force is standardized and will be exactly the same as long as the event happens on the earth, which is 9.8 m/s^2.

The direction of the pull is -70.93°, or approximately 71° South of West.

Given the vector as F= (−2980.0i^ + 8200.0j^)N

The magnitude of the pull is given by the formula below:

Magnitude of pull, |F| = √(F_x^2 + F_y^2)

Here, F_x is the force in the x-direction and F_y is the force in the y-direction. We know that:

F_x = -2980.0 N and F_y = 8200.0 N

Therefore, the magnitude of the pull is:

|F| = √(F_x^2 + F_y^2)|F| = √((-2980.0)^2 + (8200.0)^2)|F| = √(88840000) |F| = 9425.89 N

The direction of the pull can be found as follows:

θ = tan⁻¹(F_y/F_x)θ = tan⁻¹(8200.0/-2980.0)θ = -70.93°

The direction of the pull is -70.93°, or approximately 71° South of West.

When the engineer first sees the car, the locomotive is 100m from the crossing and its speed is 30m/s. If the engineer reaction time is 0.47 s what should the magnitude of the minimum deceleration to avoid an accident?

Answers

Answer:

The deceleration must have the engineer to avoid the accident is

a=-5.238 $(m)/(s^(2) )$

Explanation:

$x_(0)=100m\nv_(0)=30 (m)/(s) \nt=0.47 s$

While the engineer reacts the train continue moving so

$x_(f) = v*t= 30(m)/(s) *0.47s= 14.1 m$

$x_(t)= x_(o)+x_(f)\nx_(t)= 100m-14.1m=85.9m$

Now the final velocity have to be zero so using equation can find deceleration

$V_(f) ^(2) =V_(o) ^(2)+2*a*x_(f)\n 0= V_(o) ^(2)+2*a*x_(f)\na=-(V_(o) )/(2*x_(f))\na=-((30(m)/(s)) ^(2) )/(2*85.9m) \na=-5.238 (m )/(s^(2) ) } \n$

Answers

Answer;

the colors of light that plants require for photosynthesis

Explanation;

The color of light used for photosynthesis depends on the pigment in the plant. For example, green plants with chlorophylls and carotenoids have a maximum activity with violet-blue and red light.

White light contains various colors, including red, orange, yellow, green, blue, indigo and violet. When plants harvest light for photosynthesis, they only absorb a few colors and reflect the rest. Plants appear green because chlorophyll absorbs other colors and reflects green.
