Answer:

2682

Explanation:

Work done is given by :

Work = Force x distance

         =  mg x d

So, work done in lifting the box of 23 kg up to my waist of 1 m high is :

W = mg x d

   = 23 x 9.18 x 1

   = 211.14

Now work done carrying the box horizontally 6 meters across the room is

W = mg x d

   = 23 x 9.18 x 6

   = 1266.84

Work done in placing the box on the shelf that is 5.7 m above the ground is

W = mg x d

   = 23 x 9.18 x 5.7

   = 1203.49

So the total work done is = 211.14 + 1266.84 + 1203.49

                                          = 2681.47

                                          = 2682 (rounding off)

Answer: A while driving a car. It is unsafe

Answer:

It is a good idea to read or exchange text messages during all of the following  times except while driving a car.

Explanation:

Eating lunch and using your phone is very safe. The only way I can see it being bad is if you handed your phone to some toddlers and took it back without wiping it off!

If you're waiting for your appointment or waiting to reach your destination, then there is also no harm. As long as you are not driving the bus or you're not the doctor working on patients while texting, then this should be alright.

This leaves us with driving. The commercials tell us. Common knowledge tells us. Hopefully, parents or colleagues or even your own kids (I've had to do this to my dad countless times before) have told you this...

DO NOT TEXT WHILE DRIVING.

So many accidents happen solely for this reason. People, just put down the phone and wait 'til you're at a red light or, even better, when you reach your destination.

So no, it is not a good idea to read OR exchange text messages while driving. Any other time? Well, go ahead! But if you're in that driver seat and your currently in the road with other cars, take into consideration the fact you are not the only person there. Keep everyone safe and drop that phone!

Answer:

94 N-m

Explanation:

Joe is standing on the pedal of a bicycle. If his mass of 65 kg, the pedal makes an angle of 55º above the horizontal, and the pedal is 18 cm from the center of the chain ring. The amount of torque Joe exert is 94 N-m.

The force that can cause an object to rotate along an axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction. A vector quantity is a torque.

Torque is defined as Γ = r×F = r.F.sin(θ). In other words, torque is the cross product of the force vector, where 'θ' is the angle between r and F, and the distance vector (the distance between the pivot point and the place where force is applied).

Given in question mass 65 Kg so force, F = mg = 637 N

Distance r = .18 m and  θ = 55 so sinθ = .82

Torque = rFsin(θ) putting the values, we get

Torque = 94 N-m.

The amount of torque Joe exert is 94 N-m.

Answer:

As per the law of conservation of angular momentum, the angular velocity will be higher for the body with a lower moment of inertia and vice versa.

Explanation:

Angular momentum L of a body is given by:

[tex]L=I\times \omega[/tex]

Now when the same angular momentum is transferred to two different bodies with different moment of inertia, the body with a higher moment of inertia will have lower angular velocity and vice versa.

Answer:

Explanation:

Force on the electron due to magnetic field 's north component will be zero because both velocity of electron and direction of magnetic field are same .

Force due to downward component of magnetic field

= B q v where B is magnetic field , q is charge moving and v is velocity of charge

F = 5 .00 x 10⁻⁵ x 1.6 x 10⁻¹⁹ x 4 x 10⁷

= 32 x 10⁻¹⁷ N

acceleration = F / m where m is mass of electron

= 32 x 10⁻¹⁷ / 9.11 x 10⁻³¹

= 3.5 x 10¹⁴ m/s²

Statement C  is false. Doubling the mass doubles the acceleration is the wrong statement.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Force is defined as the product of mass and acceleration. Its unit is Newton.

Mathematically, the force is;

[tex]\rm F= ma[/tex]

If force is constant, the mass is inversely proportional to the acceleration. If the mass is double in that condition, acceleration is halved.

Doubling the mass doubles the acceleration is the wrong statement.

Hence, statement C  is false

Answer:

is there more context to go with this question? Like a photo?

Explanation:

Polyatomic ions: they are covalently bonded groups of atoms and having a positive or negative charge caused by the formation of an ionic bond with another ion.

And if your question is anything like the one I had a few days ago on a test, your answer would be something like "Both hydroxide cation (OH -) and phostphate cation (PO 4 3 -) are polyatomic ions)

Answer:

The correct answer is "625,000 J".

Explanation:

The given values are:

Mass,

m = 2,000 kg

Speed,

v = 25 m/sec

As we know,

⇒  [tex]Kinetic \ energy=\frac{1}{2} (mass \times speed^2)[/tex]

Or,

⇒  [tex]K.E=\frac{1}{2}(mv^2)[/tex]

On substituting the values, we get

⇒          [tex]=\frac{1}{2}(2,000\times 25^2)[/tex]

⇒          [tex]=1000\times 625[/tex]

⇒          [tex]=625,000 \ J[/tex]              

Answer:

D. Tidal energy is replaced naturally by the Moon's gravity.

Explanation:

The reason tidal energy is considered a renewable energy resource is that Tidal energy is replaced naturally by the Moon's gravity. The Moon's gravity creates bulges on the side of Earth that is closest and farthest from the Moon. These bulges also pull water causing high tides in those areas. As the Earth rotates these areas experience low tide while the areas that had low tide now experience high tide. This constant shift creates tidal energy every day, which is replenished naturally.

Answer:

Because no one is using that ball, so it is motionless

Answer:

No one is using the ball (dead ball) and therefore it is motionless and out of play

Explanation:

Answer:

40 m/s.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 60 m/s

Height (h) = 100 m

Acceleration due to gravity (g) = 10 m/s²

Final velocity (v) =?

The velocity at height 100 m can be obtained as follow:

v² = u² – 2gh (since the ball is going against gravity)

v² = 60² – (2 × 10 × 100)

v² = 3600 – 2000

v² = 1600

Take the square root of both side

v = √1600

v = 40 m/s

Thus, velocity at height 100 m is 40 m/s

Explanation:

Examples of static include papers on a tabletop, towel hanging on a rack, bookmark in a book , car parked on a hill.

Example of sliding include sledding, pushing an object across a surface, rubbing one's hands together, a car sliding on ice.

Examples of rolling include truck tires, ball bearings, bike wheels, and car tires.

Examples of fluid include water pushing against a swimmer's body as they move through it , the movement of your coffee as you stir it with a spoon,  sucking water through a straw, submarine moving through water.

Answer:

   f = 4.67 Hz

Explanation:

We can approximate the wave as a traveling wave, therefore the speed of the wave is constant

          v = d / t

the total distance remember, in going to the wall and back is

          d = 2 11.2 = 22.4 me

we substitute

          v = 22.4 / 4.0

          v = 5.6 m / s

now we can use the relationship between the speed of the wave, its wavelength and u frequency

          v =λ f

          f = v /λ

          f = 5.6 / 1.2

          f = 4.67 Hz
