In bullet points: explain the difference between thermal energy, heat and temperature.
sergeinik [125]
  • Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

  • Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

  • Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.

Which mixture is salt solution​
VARVARA [1.3K]

Answer:

Below

Explanation:

Salt solution, aka saline solution, is a homogeneous mixture. This means that the mixtures composition is completely uniform throughout. If you were to look at a saline solution, it would just look like plain water because the salt is dissolved (it looks the exact same in the entire mixture).

      Something like bean soup would be an example of a heterogeneous mixture. You can see all the beans and vegetables as components of one mixture.

Hope this helps! Best of luck <3

Karl likes to use cruise control when he drives on
Yanka [14]

Answer:

3.96 MINUTES

Explanation:

Karl likes to use cruise control when he drives on

the highway. After setting cruise control at 33.53

m/s (75 mph). At this speed, how long would it

take Karl to travel 8 kilometers?

VELOCITY = DISTANCE/TIME

OR

V=D/T

SO

VT=D

SO

T=D/V

THE DISTANCE IS 8 KM

THE VELOCITY IS 75 MPH

THERE ARE 1.61 KM PER MILE

SO

75M[H =

75 X 1.61 KM/H =

121 KM/HR

T=D/V

T=8/121 =0.066 HOUR =

0.066 X 60 MINUTES =

3.96 MINUTES

CHECK

75 MPH =

(75 X 1.61) KM/60 MINUTES =

120,75 KM/60 MINUTES=

2.01 KM/MINUTE

to travel 8 K,M WILL TAKE

8/2.01 = 3.98 minutes

Tyrosine absorbs maximally at 290 nm. A 0.2162 g sample containing some amount of Tyrosine was placed into a 250.0 mL volumetric
mojhsa [17]

Answer:

B. 0.069 %

Explanation:

It should be initially noted in this answer in particular that, the amino acids tryptophan and tyrosine have a very precise 280 nm absorption rate, which allows a direct A280 size of protein concentration. The 280 nm UV absorbance rate is regularly utilized to approximate protein concentration in laboratories due to its simplistic nature, its affordability and also the ease of usage.
