Answer:

1.2 mph

Explanation:

14.4 ÷ 12 = 1.2

Explanation: True

Properties that help identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage.

Answer:

Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy.

Answer:

R=V/I=6/2=3ohm

time =5minutes =5*60=300seconds

I=2A

Heat =I^2Rt=(2)^2*3*300=4*900=3600J

We have that Hence,the energy transferred in joules is mathematically given

E=0.04Joules

From the question we are told

A 6V radio with a current of 2A is turned on for 5 minutes. Calculate the energy transferred in joules

Generally the equation for the Power is mathematically given as

[tex]P=IV\\\\P=6*2\\\\P=12W[/tex]

Generally the equation for the Energy is mathematically given as

[tex]E=\frac{P}{t}\\\\E=\frac{12}{5*60}\\\\E=0.04Joules[/tex]

Hence,the energy transferred in joules is mathematically given

E=0.04Joules

Answer:

[tex]d=7970\ kg/m^3[/tex]

Explanation:

Given that,

The density of iron is 7.97 g/cm³.

We need to find the density in SI unit. The SI unit of density is kg/m³.

We know that,

1 kg = 1000 g

1 m = 100 cm

So,

[tex]7.97\ g/cm^3=7.97 \times \dfrac{(\dfrac{1}{1000})\ kg}{(\dfrac{1}{100}^3)\ m^3}\\\\=7970\ kg/m^3[/tex]

So, the density of the iron is [tex]7970\ kg/m^3[/tex].

Answer:

60Nm

Explanation:

Given data

Applied force= 200N

length of spanner= 30cm to meter

= 30/100= 0.3m

We know that the formula for the moment is

P=Fl

that is

P= force * length

P= 200*0.3

P= 60Nm

Hence the moment is 60Nm

Answer:

a --> true, b --> false, c --> true, d -->false

Explanation:

a) since it stays floating the gravity force and the upqards push is the same

b) if it's balanced the rocket won't move from the ground, the force of the rocket, has to exceed the force of gravity

c) since it's going in a diretion the force of gravity is exceeding the force pushing it up

d) since that are speeding up at a rate, meaning growing, the force is unbalanced.

========================================

Work Shown:

To find the momentum, we multiply the mass and the velocity.

m = mass = 1500 kg

v = velocity = 3 m/s

p = momentum

p = m*v

p = (1500 kg)*(3 m/s)

p = (1500*3) kg m/s

p = 4500 kg m/s

The momentum of an object is the product of its mass and velocity. Thus momentum of the car with 1500 kg and velocity of 3 m/s is 4500  kg m/s.

Momentum is a physical quantity that measure the ability to keep the force which make an object moves faster. Momentum like force is a vector quantity and is characterized with magnitude and direction.

Momentum is the product of velocity and its mass. Hence as the mass or velocity increases, momentum also increases. Increase in momentum makes the object moves faster.

Given mass of car = 1500 Kg

velocity = 3 m/s

momentum = velocity × mass

= 1500 Kg × 3 m/s

= 4500 Kg m/s.

Therefore, the momentum of the car is 4500 kg m/s.

Answer:

False

Explanation:

If you have a strong enough magnetic field all matter is magnetic. But copper is so weakly magnetic that we can't observe it without very, very large magnetic fields. So the short answer is "No, copper isn't magnetic." This can quickly be tested by trying to pick up a penny with a magnet.

Explanation:brazilian

Answer:

the distance between Kerala and Karnataka is 425 km.

Explanation:

Given;

speed of the train, u = 85 km/h

time taken for the train to travel from Kerala to Karnataka, t = 5 hours

The distance between Kerala and Karnataka is calculated as;

Distance = speed x time

Distance = 85 km/h  x  5 h

Distance = 425 km

Therefore, the distance between Kerala and Karnataka is 425 km.

Answer:

Speed changes at the rate of 24 m/s for each second over time.

Explanation:

We are told the object's acceleration is equal to 24 m/s²

Now we know that acceleration can also be defined as the rate of change of speed with time. Also speed has a unit known as m/s.

Thus, we can rephrase the acceleration in this question to mean;

Speed changes at the rate of 24 m/s for every second with time.

Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.

Explanation:

According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.

Answer:

Explanation:

One

All three statements are saying exactly the same thing.

1. one direction forces = opposite direction forces. Note forces have direction. Always remember that forces have direction and you must always say what that direction is.

2. Two is saying the same thing as one. It is just that 2 is more specific about what the direction is. Clockwise is different from anti clockwise.

3. moments are forces and distances. Forces always have direction. Distances sometimes do not. At your level of study, I don't think it does. Later on, you will learn the word displacement which always has direction and that direction must be stated.

Answer D.

15 We are told to answer just 1 or 2 questions from the same student's posting. There are 4 here, so I'm going to give you just brief answers.

You should realize by now that a loaded bus has it's center of gravity raised. The answer is B

16 A is true.

Technically anything to do with turning is a torque.

D is also true.

C is better worded than B. I would pick B as the odd one out.

17

This is rotating so they must be on the same side of the pivot point. The moments add.

20*3 + 10*2 = 60 + 20 = 80  Newton Meters. Notice C has the right numbers associated with it, but the distance is divided into a Newton. Wrong answer.

In this series of questions, moments are defined as Force * Distance.

Answer:

Anions have more electrons than protons and so have a net negative charge. Cations have more protons than electrons and so have a net positive charge. Zwitterions are neutral and have both positive and negative charges at different locations throughout the molecule.
