If the strength of the sun's magnetic field decreased from its current level, why would the temperature of sunspots increase?
Answers
Magnetic field lines emerge from one sunspot and re-enter at the other spot. Also, there are more sunspots during periods of increased magnetic activity. At ...
The temperature of sunspots increases because magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.
What is the sun's magnetic field?The magnetic field of the sun has two poles, similar to a bar magnet. Every 11 years, at the peak of the solar activity cycle, the poles flip.
The magnetic field is carried away from the sun's surface and through the solar system by a solar wind made up of charged particles. The sun is more like a fluid than a solid ball.
Thus, the magnetic field lines emerge from one sunspot and reappear in another. During periods of increased magnetic activity, there are also more sunspots.

how do sound waves behave as a solid
a. they travel faster in a solid than other mediums
b. they travel slower in a solid than other solids
c. they stop when they hit a solid
d.sound waves behave the same in any medium
Answers
Answer:
A. They travel faster in a solid than other mediums
Explanation:
Sound waves travel faster in solids because the density of solids is higher than that of liquids which means that the particles are closer together and sound can be transmitted more easily.
A particle at the origin is experiencing three forces. The first one has a magnitude of 57 lb and is directed towards (2,-4,5), while the second one has a magnitude of 32 lb and is directed towards (-1,-2,-8). If the net force is 41 lb in the direction of (-5,-1,4), what is the x-component of the third force acting on the particle (in lb)?
Answers
The x-component of the third force acting on the particle is 41.2 lb.
The given parameters;
(2, -4, 5) = 57 lb(-1, -2, -8) = 32 lb(-5, -1, 4) = 41 lbThe vector components of the forces is calculated as;
[tex]F_1 = 57, (2,-4, 5) = 57\times \frac{2i -4j+ 5k}{\sqrt{2^2 + 4^2 + 5^2} } = 8.5(2i -4j+ 5k)\\\\F_1 = (17 i -34j + 42.5k)lb\\\\\\ F_2 = 32, (-1, -2, -8) = 32\times \frac{-i -2j-8k}{\sqrt{1^2 + 2^2 + 8^2} } = 8.3(-i-2j-8k)\\\\ F_2 = (-8.3i - 16.6j - 66.4k)lb\\\\\\ F_{net}= 41, (-5, -1, 4) = 41\times \frac{-5i -j+ 4k}{\sqrt{5^2 + 1^2 + 4^2} } = 6.5(-5i-j+ 4k)\\\\ F_{net} = (-32.5i -6.5j+ 24k)lb[/tex]
The x-component of the third force is calculated from the resultant of the forces;
[tex]F_1+F_2 + F_3 = F_{net}\\\\F_3 = F_{net} - (F_1 + F_2)\\\\F_3 = (-32.5i -6.5j + 24k) - (17i -34j + 42.5k) - (-8.3i -16.6j -66.4k)\\\\F_3 = (-32.5 -17 + 8.3)i +(-6.5 + 34+ 16.6)j + (24 -42.5+66.4)k\\\\F_3=(-41.2 i) +(44.1)j + (47.9)k\\\\F_3 = (-41.2i + 44.1 j + 47.9k)lb[/tex]
Thus, the x-component of the third force acting on the particle is 41.2 lb.

A man is trying to push a box across a table. He pushes on the box with 5 N and the
table provides a frictional force of 1 N. What will be the net force on the box?
1) 4 N
2) 5 N
3) 6 N
4) Not enough information has been given
Answers
Answer:
4 Newton
Explanation:
because you minus 1 Newton from 5 newton
The net force on the box is equal to 4N. Therefore, option (1) is correct.
What is the net force?The net force can be described as the vector sum of forces acting on a particle or object. The net force can be defined as a single force showing same the effect of the original forces on the particle's motion. Net force gives the same acceleration as all those actual forces together.
The net force becomes the resultant force. It has the same effect on the rotational motion as all actual forces taken together by the object. Force is a vector quantity as it has a magnitude and a direction.
In the given problem, the applied force is in the opposite direction of the frictional force so we can find the net force by subtracting these two forces.
Given, the applied force to push the box = 5N
The frictional force on the box, = 1 N
The net force on the box = 5N + (-1N) = 4N

Answer:
The marble will take 8.813 seconds to hit the ground.
Explanation:
The marble will fall according to this motion equation: y(final) = y(initial) + v(initial)×t + 1/2×a×t×t
y(final)=0 m, the marble's final position in relation to the ground
y(initial)=381 m, the marble's initial position in relation to the ground
v(initial)=0 m/s (meters per second), the marble's initial velocity (speed with direction) when fall first begins
t=? seconds, this is the amount of time that passes while falling, the variable in this problem
a=-9.81 m/s/s, the rate at which the velocity of the marble changes, acceleration. On Earth, neglecting friction, acceleration is a constant at negative 9.81 meters per second squared
Plug the values into the equation: 0= 381 + 0t + 1/2(-9.81)(t)(t)
Subtract 381 from both sides and disregard 0t because it has no value and no longer matters: -381= 1/2(-9.81)(t)(t)
Multiply out the equation: -381= -4.905(t)(t)
Divide both sides by -4.905 to isolate the variable: 77.676=(t)(t)
Find the square root of both sides: t=8.813 seconds

A rocket traveling through space with a constant velocity of 10 m/s fires up a booster. The booster accelerates the rocket at a rate of 5 m/s. What distance in meters has the rocket traveled within 12 seconds after the booster is turned on?
Answers
The distance traveled by the rocket after the given time period is 480 m.
The given parameters;
velocity of the rocket, v = 10 m/sacceleration of the rocket, a = 5 m/s²time of motion of the rocket, t = 12 sThe distance traveled by the rocket after the given time period is calculated from the second kinematic equation of as shown below;
s = ut + ¹/₂at²
s = (10 x 12) + (0.5 x 5 x 12²)
s = 120 + 360
s = 480 m

A 5.0 kg cannonball is fired horizontally at 68 m/s from a 15-m-high cliff. A strong tailwind exerts a constant 12 N horizontal force in the direction the cannonball is traveling. What is the extra distance (d)?
Answers
Answer:
3.7 m
Explanation:
ASSUMING this means extra distance beyond where the cannonball would land WITHOUT the wind assistance but in general ignoring air resistance. Hmmmmmm...tricky
The ball drops from vertical rest to ASSUMED horizontal ground 15 m below in a time of
t = √ (2h/g) = √(2(15)/9.8) = 1.75 s
Without the tail wind, the ball travels horizontally
d = vt = 68(1.75) = 119 m
The tailwind exerts a constant acceleration on the ball of
a = F/m = 12/5.0 = 2.4 m/s²
The average horizontal velocity during the flight is
v(avg) = (68 + (68 + 2.4(1.75)) / 2 = 70.1 m/s
so the distance with tailwind is
d = v(avg)t = 70.1(1.75) = 122.675 m
The extra distance is 122.675 - 119 = 3.675 = 3.7 m
