Answer:

3600 kg

Explanation:

From the question,

Density = Mass/Volume

D = M/V.............................. Equation 1

Where D = Density of the substance, M = mass of the substance, V = Volume of the subtance.

Make M the subject of the equation

M = D×V ............................ Equation 2

Given: D = 1200 kg/m³, V = 3 m³.

Substitute these values into equation 2

M = 1200×3

M = 3600 kg.

Hence the mass of the substance is 3600 kg

Permanent magnets are important for their industrial uses especially when it comes to power generation and electric motors. The induction process for turbines and generators needs permanent magnets to turn mechanical motion into energy.

Exposing magnetized magnets to opposing external fields produces a demagnetizing effect. This effect is most apparent in permanent magnet materials having a non-linear demagnetization curve, such as Alnico. ... Other factors such as SHOCK and VIBRATION have very little effect on today's permanent magnet materials.

Answer:

sping constant is the force needed to stretch or compress a string

The formula:

Fs=-kx

Fs= force

k= spring constant

x= amount of extension

Answer:

The moon has no atmosphere

Explanation:

The temperatures on the surface of the Moon vary much more than those on Earth because the moon has no atmosphere (third answer in the list), and therefore there are no molecules that could retain residual heat and make the change from day to night a softer transition.

Answer:

5 m/s

hope it helps:) u're welcome

The velocity of the duck must be 15 m/s towards the east which is explained below.

The force on a moving charge with some velocity under a magnetic field is given by:

F = qv×B

here q is the charge on the object

v is the velocity of the object

B is the magnetic field

v×B gives the direction of the force

B is towards the north, and Force is directed upwards, then velocity v should be towards the east.

3×10⁻¹¹ = 4×10⁻⁸× v × 5×10⁻⁵

v = 15 m/s

Although X-rays have many benefits, they can be dangerous to human health because they are short wavelength, high frequency, with photons sufficiently energetic to damage DNA molecules.

Answer:

A. True it's right solids have a definite shape and volume.

Answer:

Required distance is 103 miles and the required time is 1 hour

Explanation:

Given;

speed of the car, v = 103 miles per hour

Speed is the given as the ratio of distance traveled to time taken for the motion.

The distance it will take another car to catch up to them from a complete stop is 103 miles and the time it will take the car is 1 hour.

Therefore, required distance is 103 miles and the required time is 1 hour.

Answer:

Displacement method of volume measurement is no suitable

Explanation:

Displacement method of volume measurement is no suitable for the objects that do not get immersed into the water completely because of the hindrance in accuracy of the measurement.

The mass would have centripetal acceleration a given by

a = v ² / R

where

v = tangential speed of the mass

R = length of the string

By Newton's second law, a maximum tension of F = 135 N would apply an acceleration of

135 N = (2.0 kg) a   →   a = 67.5 m/s²

which requires a tangential speed v of

67.5 m/s² = v ² / (1.10 m)   →   v = √((67.5 m/s²) (1.10 m)) ≈ 8.62 m/s

Its 50 points for me but ok 100 4 u nice uh... here. Bringing the 1996 Summer Olympic Games to Atlanta was a long shot. Athens, Greece, was the sentimental favorite to host the centennial games, and tension was palpable as IOC President Juan Antonio Samaranch made the announcement back on Sept. 18, 1990.

"The International Olympic Committee has awarded the 1996 Olympic Games to the city of ... Atlanta," Samaranch revealed.

That announcement launched more than $1 billion of construction projects, from Olympic venues to housing for the athletes. Now, on the 15th anniversary of the games, Atlanta sees both gains and losses from the international event. Bringing the 1996 Summer Olympic Games to Atlanta was a long shot.

One of the most prominent legacies of the games is Centennial Olympic Park in the heart of Atlanta. The 21-acre plaza glistens in what was an area of urban decay, and children run and linger in the fountain.

Harvey Newman, a professor of public policy at Georgia State University, says the park brought economic development downtown.

"The area surrounding the park has added major hotels, condominiums, new office structures and, of course, people continue to flock to enjoy the Olympic rings fountain," Newman says.

Answer:

The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.

Answer:

Explanation:

Yes , their displacement may be equal .

Suppose the displacement is AB where A is starting point and B is end point .

The car is covering the distance AB by going from A to B on straight line . On the other hand plane goes from A to C , then from C to D and then from D to B . In this way plane reaches B from A on a different path which is longer than path of the car . In the second case also displacement of plane is AB . In the second case distance covered is longer but displacement is same that is AB .

Answer:

The speed is 1.35 m/s

Explanation:

(m1+m2) vi= m1+m2v2

(50+1.5) (3.5)=50 (5+v2) +1.5 v2

180.25= 250+ 51.5 v2

180.25- 250+ 51.5 v2

-69.75= 51.5 v2

v2= -1.35 m

Answer:

p = 0

Explanation:

Given that,

Mass of beetle, m = 750 kg

It was rest. It means its speed is equal to 0.

The momentum of an object is equal to the product of mass and velocity. So,

p = mv

p = 750 × 0

p = 0 kg-m/s

So, the momentum of the beetle is 0 kg-m/s.
