mark me brainy plz

answer:

u =11

Explanation:

brackets were inserted in the 1st step,to make it simpler as multiplication is done first, before addition.

hope this helps:))

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

Explanation:

Momentum P=mass×velocity

1000=800×velocity

1000=800V

V=1000/800=2.5m/s

Answer:

F = m x a

Explanation:

F = force

m = mass of an object

a = acceleration

Answer:

Explanation:

Density is calculated by

dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples' volume.

Answer:

Explanation:

Since there is no common factor besides 1, the formula is already the empirical formula for this compound.

The momentum of an object is 30 kgm/s . This can be calculated by using momentum formula see description below.

It is defined as the product between mass and velocity. Its symbol is p.

It is given by:

p = m * v

What information do we have?

Mass = 5kg

Velocity = 6 m/s

To find:

Momentum=?

On substituting the values:

p = m * v

p =5 kg * 6 m/s

p = 30 kgm/s

Thus, the momentum of an object is 30 kgm/s.

Explanation: True

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

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.

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:. 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:

5 kg

Explanation:

Acceleration = 6 m/s^2

Force = 30 N

Force = mass * acceleration

mass = force / acceleration

mass = 30 / 6

mass = 5 kg

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].
