Answer: 15000 J

Explanation:

Given ;

Temperature change, dθ = 10

Mass of substance, m = 5 kg

Specific heat capacity, C = 300 j/kg°C

Quantity of heat, Q required is obtained using the relation ;

Q = mCdθ

Q = 5kg * 300 j/kg°C * 10°C

Q = 5 * 300 J * 10

Q = 15000 J

If your heart is beating at 76. 0 beats per minute, what is the frequency of your heart's oscillations in hertz?
nikitadnepr [17]

If the heart is beating at 76. 0 beats per minute, the Frequency of heart's oscillations in hertz is 1.25 Hertz.

The Frequency is defined as the number of oscillations completed in 1s.

Our heart beats continuously giving rise to the frequency of the heart.

Measuring frequency would be possible if we measure the time in seconds.

75 beats per minute means that 75 beats occur in 60s.

Frequency = Number of beats / Total time taken

Frequency = 75 / 60

Frequency = 1.25 Hz

Hence, number of beats per second is 1.25 Beats.

Beats per second or Cycles per second is same as the frequency of oscillation called as Hertz (Hz)

Hence, frequency of the heart oscillation is 1.25 Hertz (Hz).

What is the identity of a sample that has a volume of 92.5 cm3 and a mass of 249.8 g?
denpristay [2]
Here, We know, Density = Mass / Volume
Here, mass = 249.8 g
volume = 92.5 cm³

Substitute their values, 
d = 249.8 / 92.5
d = 2.7 g/cm³

In short, Your Answer would be "Aluminum" 

Hope this helps!

Describe a situation in which an object's speed is constant but its velocity is changing.
Olegator [25]
1) If the object changes directions with the same speed, it will be changing its velocity, because velocity is a vector, which depends on both magnitude and direction. Speed is just magnitude regardless of direction.

2) Rotational motion.
