-- It takes 100 calories of heat to make 10 grams of the stuff 20° warmer.

How much of the heat warms each gram ?

-- It takes 10 calories of heat to make each gram of the stuff 20° warmer.

How much of the heat warms that gram each degree ?

-- It takes 1/2 calorie of heat to make each gram of the stuff 1° warmer.

The specific heat of that stuff is

(1/2 calorie) per gram per °C.

That's choice-3 .

How are the spiral arms of the milky way detected?

Step2247 [10]

The spiral structure emerges when galactic clusters (open), H II regions and O & B type stars (young stars) are used as tracers. We know this to be true as other pinwheel galaxies exhibit the same patterns across these tracers as in the milky way.

A 150kg person stands on a compression spring with spring constant 10, 000 N/m and norminal.Length of 0.50.What is the togal len

Eva8 [605]

Answer:

Total length of spring 0.647 m

Explanation:

We have given mass of the person m = 150 kg

Acceleration due to gravity $g=9.8m/sec^2$

Spring constant k = 10000 N/m

Nominal length of spring = 0.50

According to hook's law

$mg=kx$

$150\times 9.8=10000\times x$

x = 0.147 m

So total length of spring = 0.50+0.147 = 0.647 m

In 2014, about how far in meters would you have to travel on the surface of the Earth from the North Magnetic Pole to the Geogra

pogonyaev

Answer:

267.07 km

Explanation:

We have given the radius of the earth = 6378.1 km

In 2014 the difference between the magnetic north pole and geographical north pole is 2.40°

2.40° $=2.40\times \frac{\pi }{180}=0.041866 radian$

We know that linear distance is given by $S=R\Theta =6378.1\times 0.041866=267.07km$

So we have to travel 267.07 km in going from magnetic north pole to geographic north pole

What happens as a result of the pulses passing by each other?

nadezda [96]

Answer:

After pulses pass through each other, each pulse continues along its original direction of travel, and their original amplitudes remain unchanged.

Explanation:

Constructive interference takes place when two pulses meet each other to create a larger pulse.
