Answer: Distance

Explanation:

Distance is the unit of the light year and we can measure the light year by using the distance measurement. In one year, the light can travel at the velocity of 300000 km (Kilometer) in each seconds. Therefore, in every one year, they can travel 10 trillion kilometers.

Light year is also denoted as ly and it travel in one year at the empty space. The distance of the stars are generally measured in the light year as the objects in the space are mostly far away and they are using the small distance unit like astronomical unit.

A 65-cm segment of conducting wire carries a current of 0.35 A. The wire is placed in a uniform magnetic field that has a magnit

dimaraw [331]

Answer:

e) 67°

Explanation:

the force on the wire can be calculated using the expression below

F = BILsinФ

But we are looking for the angle between the wire segment and the magnetic field, then we can make Ф the subject of the formula from the above expresion, then we have,

Ф =sin⁻¹ (F/BIL)

The parameters is defined as

I =current that is been carried by the wire= 0.35 A

Ф = angle between the wire segment and the magnetic field, which is the unknown?

L = length of the wire=65 cm

B = magnetic field = 1.24

F= force on the wire = 0.26 N,

Ф =sin⁻¹ (F/BIL)

Ф =sin⁻¹ X .....................eqn(#)

Where X= (F/BIL)

We can calculate for X= (F/BIL), from eqn(#) by substituting value of Force, Lenght and

magnetic field

X=(F/BIL)= 0.26/(1.24×0.35×0.65)

= 0.26/0.2821

=0.922

Then substitute X into eqn (Ф =sin⁻¹ X)

Then

Ф =sin⁻¹ (0.922)

Ф=66.42°

Ф=67° approximately

Therefore, the angle between the wire segment and the magnetic field is 67°

A crane raises a 12,000 N marble sculpture at a constant velocity onto a pedestal 1.5 m above the ground outside an art museum.

Simora [160]

For the work, applicate formula:

$\boxed{\boxed{\green{\bf{W = F\times d}}}}$

According our data:

Replacing:

W = 12000 N * 1,5 m

Resolving:

W = 18000 J

The work done is <u>18000 Joules.</u>

If an object falls with constant acceleration, the velocity of the object must continually change by varying amounts, depending

Ierofanga [76]

Answer:

continually change by the same amount each second

Explanation:

We all are aware with the fact that a car speeds is increased when we put our feet on the accelerator. The rate at which the particle's velocity change with time is called its acceleration. If the particle's velocity changes with constant rate, then its rate is called the constant acceleration.

Since the basic units are meter and seconds. And the SI unit of velocity is $m/s$ and acceleration's SI unit is $m/s^{2}$

For example if the velocity is change from 2 to 4 m/s in 1 sec its acceleration is $2m/s^{2}$ and again its velocity is change with 4 m/s to 6 m/s will again give constant acceleration in 1 s is $2m/s^{2}$ .
