Answer:

I believe the answer is D.

Explanation:

It would have been helpful if there had been more information included with this problem, but it would make sense that the answer is D. If there is a winter between time 1 and 3, bison that are not well-suited to the weather, (skinny and smooth) will die off, and only the ones well-suited to winter weather will survive to produce offspring.

Which of the following maxims would apply to a person with a Type A personality?

lozanna [386]

The correct answer is C. Lost time is never found again

Explanation:

One of the most relevant personality theories is Type A and Type B personality theory that proposes two main types of personalities by grouping different personality traits. In the case of Type A personality, this refers to individuals that are very organized, impatient, and concerned with time and goals. On the opposite, Type B personality includes individuals that are more relaxed in different aspects.

According to this, one maxim that applies to Type A personality is "Lost time is never found again" because people with this personality are concerned about time and therefore, loss of time is considered highly negative by them. Also, due to their ambitions and concern with goals they want to avoid losing time as this is equivalent to work, money, goals, etc.

The box leaves position x=0x=0 with speed v0v0. The box is slowed by a constant frictional force until it comes to rest at posit

SpyIntel [72]

Answer:

Magnitude of the Frictional force = (mv₀²)/2x₁

Explanation:

For the frictional force to stop the box, it has to produce the deceleration of the box; thereby being the opposing force to the box's motion.

According to Newton's first law of motion

Frictional force = (mass of the box) × (deceleration experienced by the box)

Let the mass of the box be m

Then,

Frictional force = ma

Then we can obtain the deceleration using the equations of motion

v² = u² + 2ax

u = Initial velocity = v₀ m/s

v = Final velocity = 0 m/s (since the box comes to rest at the end)

x = horizontal distance covered = (x₁ - x₀) = x₁ (since x₀ = 0)

a = ?

v² = u² + 2ax

0 = (v₀)² + 2ax₁

2ax₁ = - v₀²

a = - (v₀²)/(2x₁) (minus sign, because it's a deceleration)

Magnitude of the Frictional force = ma = (mv₀²)/2x₁

If the direction of a magnetic field around a vertical electrical wire is counter clockwise, what direction is the electrical cu

strojnjashka [21]

Direction of the current:

From the bottom of the wire to the top

Explanation:

The magnetic field produced by a current-carrying wire forms concentric circles around the wire; its magnitude is given by

$B=\frac{\mu_0 I}{2\pi r}$

whrere

$\mu_0$ is the vacuum permeability

I is the current in the wire

r is the distance from the wire

The direction of the magnetic field produced by a current-carrying wire can be found by using the right-hand rule:

- The thumb of the right hand is placed in the same direction as the current

- The other fingers, wrapped around the thumb, give the direction of the magnetic field

In this case, the wire is vertical and the magnetic field is counter clockwise (looking from the top), therefore we need to put the thumb from the bottom to the top in order to get the same direction for the field: therefore, the direction of the current is

From the bottom of the wire to the top
