"Acceleration" means any change in speed or direction of motion. 
If the object is known to be accelerating even though it's traveling
in a straight line, then we know that its speed must be changing.

An ice block measuring 5cm by 5cm by 5cm has a desity of 5g/cm3. What is the mass of the ice block?
Svetradugi [14.3K]


Density = (mass) / (volume)

Volume of your block = (5cm x 5cm x 5cm) = 125 cm³

5 gm/cm³ = (mass) / (125 cm³)

Multiply each side by (125 cm³):  Mass = 625 gm

Note: 
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there.  The density of water ice is not
5 gm/cm³.  In fact, it's a little less than 1 gm/cm³.  That's why
the ice floats in your soda.

A bowling ball and a soccer ball are both rolling at the same speed. Which has more kinetic energy and why?
MissTica
Ek = 1/2 mv^2

If they are travelling at the same speed the one with the larger mass will have more kinetic energy as kinetic energy and mass are proportional.

Can anybody helpp????
Oliga [24]

Answer: white shirt-reflect

top hat- reflect

elepahnt- i think absorb im quite sure

Explanation:

Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. Different shirts with different colors will absorb light of different wavelength. Black shirt will absorb all colors of light while white shirt will reflect all colors of light. thats why on a hot day you wouldnt want to wear a black t shirt.

Name an acid which is highly corrosive and should never be tested by mouth.​
Vitek1552 [10]

Answer:

We all know that HCI is highly corrosive mineral acid. It's produced naturally in our (Human being) Stomach

It (HCI) is produced by the gastric glands in stomach. HCI activates the enzyme Pepsin and creates an acidic medium which kills the bacteria which might have entered while digestion & also making it simpler for further digestion.

HCI does not harm our stomach because the gastric gland also produces Mucus which helps in preventing the damage of inner wall (layer) of stomach from the action of this Acid.
