Answer:

The acceleration DUE to gravity depends on the mass of the body, the distance from the CENTER of mass, and a constant G, which is called the "universal gravitational constant". ... The acceleration due to gravity on the surface of the moon is 1.620 m/s2. 2) The radius of the Earth is 6.38 X 106 m.

ANSWER:

SPEED =26.7-6.7

=20.0m/sec

THEREFORE you can ALSO WRITE it as =20m/sec

distance=800m

time=?

therefore,

speed=distance/time

20=800/time

time=800/20

time=40sec

Answer:

the and is 35°c

Explanation:

M1 * C * T1 =M2 * C * T2

M1 = M2 = 50g

let final TEMPERATURE be = T

T1 = (T-20° celcious)

T2 = (40° celcious-T)

SINCE M1 = M2 and C=C

FINAL EQUATION (T-20=50-T)

2T=50+20

2T=70

T=35

FINAL TEMP. = 35° c

assume no HEAT is lost or GAINED

Answer:

Heat = MASS × specific heat × TEMPERATURE change

Q = m C ΔT

Given:

q = 337500 J

m = 50 KG

ΔT = 15°C

Substitute:

337500 J = (50 kg) C (15°C)

C = 450 J/kg/°C

Specific heat is usually RECORDED in J/g/°C or kJ/kg/°C.  Converting:

C = 0.45 J/g/°C = 0.45 kJ/kg/°C

A is the correct ANSWER!

ANSWER:

here is your answer

Coil 1 enters the North Pole of the MAGNETIC field and current flows through Commutator side 1 to Brush 1. ... In that way, the commutator converts AC to DC because it NEVER allows current to change direction in the brushes. AC current rises and FALLS in a cycle.

Answer:

2 SIGNIFICANT FIGURE

Explanation:

Because there are TWO significant figure in PRICE of COPPER

Answer:

here,

mass of iron=100KG

mass of cotton=100 KG

here for 100kg, amount of cotton will be more than the amount of iron

that is VOLUME of 100 kg cotton is more than the volume of 100 kg iron as its DENSITY is more than cotton.

here the machine was not a weighing machine. rather it was a machine to calculate volumes

Newton's law of universal gravitation is USUALLY STATED that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and INVERSELY proportional to the square of the distance between their CENTERS.

Answer:

EXPLANATION:

NET force is zero and F1= K. -4.5/x.

F2= k. 16.5/9+x.

F1=f2 after solving we will get x=9cm by -4uc

Answer:

Definition of Celsius

Celsius scale is the part of the metric system and is used to measure the temperature in many countries. Celsius was earlier known as centigrade scale; it is denoted as°C (the Celsius scale). This is the easiest method to understand the temperature reading.

Celsius was introduced in mid-1700 by ‘Andres Celsius‘. Taking water as the base, they have set certain standard values, which is clear to figure out. LIKE the freezing point of water is 0°C and the boiling point is 100°C. The normal human body temperature is 32°C, and the absolute zero value is set at -273.15°C.

As we said that the values are interconvertible, by APPLYING some easy calculations, so here is the way to change the Celsius to Fahrenheit.

°C to °F: Multiply by 9, then divide by 5 and then add 32.

Formula is written as: (°C × 9/5) + 32 = °F or precisely (°C × 1.8) +32.

Example: How to convert 28°C to Fahrenheit (°F).

FIRST step: 28°C × 9/5 = 252/5 = 50.4.

Second step: 50.4 + 32 = 82°F.

Explanation: From the above example we can it is mandatory to explain that why we have converted the temperature by taking the value as 9/5 and then adding with 32. So if we look at the scale of the Celsius and Fahrenheit, their scale starts at 0°C and 32°C (0 vs 32), respectively, so here we have added 32. Secondly, the scale rises at the rate of 100°C and 180°F (100 vs 180), so again we need to multiply, and 180/100 = 9/5. So this is very easy to calculate.

Definition of Fahrenheit

This is another parameter to measure temperature but nowadays used in United STATES (US) and few of its territories. It was originated by the physicist ‘Daniel Gabriel Fahrenheit‘ in 1724. The relative’s values like freezing and boiling point of water make the difference. According to this parameter, the boiling point of the water is 212°F and melting point 32°F, and so it makes the difference of the 180 degrees exactly.

The Celsius scale and the Fahrenheit scale coincides at -40°, which is same for both. Even normal human body temperature is 96° on this scale and the absolute zero –459.67°F.

Likewise, the values of Celsius to Fahrenheit is interconvertible, and the same can be done from Fahrenheit to Celsius.

°F to °C: Subtract 32, then multiply by 5, then divide by 9.

Formula is written: (°F – 32) × 5/9 = °C or precisely (F – 32)/1.8.

Example: How to convert 98.6° Fahrenheit into Celsius (°C)

First step: 98.6°F – 32 = 66.6.

Second step: 66.6 × 5/9 = 333/9 = 37°C.

And so from the above example, it is EASILY understandable to convert the given values in Celsius to Fahrenheit

Answer:

TU he QUESTION me hi to he it is along X AXIS

ANSWER:

i THINK you re correct

Explanation:

The torque is DEFINED as the product of the charge and electric field acting on the charge.

• The vector notation of the torque is τ=p×E.
• The direction on both p and E is acting perpendicular to both.

• The electric field is non- UNIFORM then the net force acting on them is not equal to zero.
• The electric field in both CASES are increasing with POINT P. But the DIFFERENCE came in the direction when they are in parallel, then both are in same direction.
• When they are in perpendicular the direction is opposite to each other.

Explanation:

As the ULTRASONIC WAVES come back after 5 seconds, they will REACH the submarine after 2.5 seconds when emitted. Thus , the time is 2.5 second, the speed is 1400 m/s , so the DISTANCE will be : speed ×time = 1400× 2.5 = 3500 m

Ultra-high-energy GAMMA ray. Ultra-high-energy gamma rays are gamma rays with photon energies higher than 100 TeV (0.1 PeV). They have a FREQUENCY higher than 2.42 × 1028 Hz and a WAVELENGTH shorter than 1.24 × 10−20 m

Answer:

1. CONCAVE mirror

Explanation:

We know for a SHM velocity is

v=ω[√(A²-x²)]

and MAX SPEED is vₘ=ωA

by question speed is Aω/2

∴A²ω²/4 =A²ω²-ω²x²

solving we GET x²=3A²/4

so its displacement is ±√3A/2 from mean position

Answer-The work that must be done on q_3q

by an EXTERNAL force \displaystyle \vec{F}_{ext}

F

ext

is equal to the DIFFERENCE between two quantities: the potential energy U associated with q_3q

when it is at x = 2a and the potential energy when it is infinitely far away.

The second of these two is zero, so the work that must be done is equal to U. The DISTANCES between the charges are r_{13}=2ar

=2a and r_{22} = ar

=a, so

\displaystyle W = U = \frac{q_3}{4 \pi \varepsilon_0} \left( \frac{q_1}{r_{13}} + \frac{q_2}{r_{23}}\right)W=U=
