A 1.00 x 109 kg object is raised vertically at a

DerKrebs [107]

Answer:

P = 3.92 10¹⁰ W

Explanation:

The power is data by the expression

P = W / t

the work of a force is

W = F. y

the bold ones represent vectors. In this case the displacement is vertical upwards and the vertical forces upwards, therefore the angle is zero and the cos 0 = 1

W = F y

we substitute

P = F y / t

P = F v

as the body rises at constant speed the acceleration is zero and from the equilibrium condition

F -W = 0

F = mg

we substitute

P = m g v

let's calculate

P 1.00 10⁹ 9.8 4

P = 3.92 10¹⁰ W

Half Time At 3:00 the hour hand and the minute hand of a clock point in directions that are 90.0

jenyasd209 [6]

Answer:

3 : 08 : 10.9

Explanation:

assuming a 12 hour clock

angular velocity of the hour hand is 2π/(3600(12)) rad/s

angular velocity of the minute hand is 2π/3600 rad/s

difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s

45° = π/4 radians

This angle is covered in a time of

π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s

or about 8 minutes 10.9 s

The Pacific Plate is moving 29 mm/year toward the north and 20 mm/year toward the west relative to the North American Plate. Sho

adell [148]

Answer:

7 mm per year

Explanation:

It is given that :

The Pacific plate is moving towards north at = 29 mm per year

The Pacific plate is moving towards west at = 20 mm per year

We have to calculate the total relative motion towards the northwest.

So we have to find the resultant of the two motions.

Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.

Therefore, finding their resultant,

$R^2=(29)^2+(20)^2$

$R^2=(49)^2$

R = 7

Therefore, total relative motion towards the northwest is 7 mm per year.

Two shuffleboard disks of equal mass, one of which is orange and one of which is yellow, are involved in an elastic collision. T

Ede4ka [16]

Answer:

v₁ = 5 m/s

Explanation:

We can use the law of conservation of momentum here:

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

where,

m₁ = m₂ = m = mass of each disk

u₁ = initial speed of yellow disk = 0 m/s

u₂ = initial speed of orange disk = 5 m/s

v₁ = final speed of yellow disk = ?

v₂ = final speed of orange disk = 0 m/s

Therefore,

$m(0\ m/s+5\ m/s)=m(v_1+0\ m/s)\\\\$

<u>v₁ = 5 m/s</u>
