Jake lifted a 10-kg bell by a distance of 0.50 meters in 0.50 seconds. How much power did Jake use?​

Answers

Answer:

10 watts

Explanation:

first calculate work.

Work =force×distance cos thita

10Kg×0.50M cos 0= 5joules

Therefore, Power=Work÷ Time

Therefore, 5joules÷0.50s=10 watts.

What is the major difference between metallic bonding and ionic bonding?


Answers

Answer:

The key difference between ionic bonding and metallic bonding is that the ionic bonding takes place between positive and negative ions whereas the metallic bonding takes place between positive ions and electrons.

Explanation:

About (metallic bonding) → Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.

About (ionic bonding) → Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds

A jet plane is traveling with a velocity of 720 kilometers/hour due north. There is a crosswind of 40 kilometers/hour from the east. Find the resultant velocity and the direction of the jet plane.

A.
720 kilometers/hour in the direction of 3.2° west of north
B.
720 kilometers/hour due north
C.
721 kilometers/hour in the direction of 3.2° west of north
D.
520 kilometers/hour in the direction of 45° east of north

Answers

Answer:

Option c is correct v = 721 km/h θ = 3.2°

Explanation:

In pic is further explanation: A triangle means division

The magnitude of the velocity of the plane can be found by calculating the resultant of the two velocities:

 R= [tex]\sqrt{(720km ÷ h^)^2 + (40km ÷ h)^2) = 721.1 km ÷ h}[/tex]

The direction can be found as follows:  

0 = tan^-1 (720km ÷ h/40km ÷h) = 86.8

where 720 km/h represents the velocity towards north, while 40 km/h represents the velocity towards west, so the angle is measured with respect to east. Therefore:

the direction is 86.8*north of west

second intervals of
time.

Answers

The vertical component of the velocity after the given time is -9.8 m/s while the horizontal component of the velocity is 16 m/s.

The given parameters;

initial horizontal velocity, vₓ = 16 m/sinitial vertical velocity, [tex]v_y =0[/tex]time interval 1 seconds

The components of the velocity can be horizontal or vertical velocity.

The vertical component of the velocity is affected by acceleration due to gravity while the horizontal component of the velocity is not affected by gravity.

The vertical component of the velocity is calculated as;

[tex]v_y = v_0_y -gt\\\\v_y = 0 - (1\times 9.8)\\\\v_y = -9.8 \ m/s[/tex]

The horizontal component of the velocity is constant since it is not affected by gravity.

The horizontal component of the velocity = 16 m/s

Thus, the vertical component of the velocity after the given time is -9.8 m/s while the horizontal component of the velocity is 16 m/s.

Answers

If the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.

What is ohm’s law?

When all physical parameters and temperature are constant, Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

This current-voltage connection may be expressed mathematically as,

The Equation of Ohm's Law;

V∝I

V'∝I'

Hence, if the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.

A jet airplane is in level flight. The mass of the airplane is m = 8930 kg. The airplane travels at a constant speed around a
circular path of radius R = 8.01 mi and makes one revolution every T = 0.106 h. Given that the lift force acts perpendicularly
upward from the plane defined by the wings, what is the magnitude of the lift force acting on the airplane?
At what angle is the airplane banked?

Answers

Answer:

Explanation:

The lift force will have a vertical component equal to the weight of the plane and a horizontal component sufficient to supply the needed centripetal accleration.

R = 8.01 mi = 12891 m

ω = 2π/T =  2π/(0.106(3600)) = 0.016465 rad/s

F = m√(g² + (ω²R)²)

F = 8930√(9.81² + (0.016465²(12891))²)

F = 8930√(9.81² + 3.49²)

F = 92,996.480...

F = 93.0 kN

θ = arctan(3.49/9.81) = 19.6°

1 oto chạy trên 1 đoạn đường thẳng từ địa điểm A đến địa điểm B phải mất 1 khoảng thời gian t, Tốc độ của oto trong nửa đầu của khoảng thời gian này là 60km/h và trong nửa cuối là 40km/h. Tính tốc độ trung bình của oto trên cả đoạn đường AB

Answers

Answer:

Explanation:

t = (½d)/60 + (½d)/40

t = (½d)/60(2/2) + (½d)/40(3/3)

t = (½d)2/120 + (½d)3/120

t = (½d)5/120

t = (½d)/24

t = d/48

v = d/t

v = d / (d/48)

v = 48 km/h

Answer:

The correct answer is C - 7.8 < 7 5/6 < 7.9

Step-by-step explanation:

First, convert 7 5/6 to decimal form --> 7.83.

If you don't know how to convert, think about what 5/6 is equal to and put it in decimal form. Add your decimal to the whole number, and there is your answer.

7.83 is in between 7.8 and 7.9, so it must be the answer.

Xf= ?

t = ?

Step 3  * A 2 dimensional problem so break it down into x component and y component

 

 

Step 4   x component  

 

x= [Vox ][cos 30o][t]

x= [800m/s][cos 30o][tsec]

x=[692.8m/s][tsec]       <---------------Need t

 

Step 5 y component
