1 answer:

7 0

The solution to your problem is as follows:

5km/h2 x 1 h/60 min x 1 min/60 sec x 1000m/km = 1.39 meters per second change each second.

Therefore, the speed change each second is 1.39 meters per second change each second.

When a chemical equation contains the same number of atoms on both sides, the equation is balanced.

andreyandreev [35.5K]

Answer:

True.

The equation is balanced.

Explanation:

A balanced equation of any particular reaction is often identified when the significant total number of atoms in each of the significant elements present in the reactant side often quoted as the left side is identically same as the number of atoms present in the adjacent side which is the product side also known as right side of the present reaction. Hence it generally implies for a balanced equation to be, the number of moles on one side of the reactant side as well as the product side should also be similar i.e equal.

Example

Here,

No of atoms present in reactant side = 2

No of atoms present in product side= 2

Therefore, Atoms present in the reactant side= atoms present in the product side

Hence, the equation mentioned above is chemically balanced on both sides.

Eddy believes that aliens make him walk 2 miles every day from his house to the store. this is an example of:______.

emmasim [6.3K]

Answer:

Eddy believes that aliens make him walk 2 miles every day from his house to the store. this is an example of:Hallucinations.

Explanation:

Hallucinations are sensory impressions that come from the mind yet seem realistic. Every one of the five senses may be affected hallucination. One could, for instance, hear a voice that nobody else in the area can hear or seeing of a fake image. When someone is hallucinating, they will perceive things in their brains that they believe to be real but are actually not. Only the mind can produce these ideas. These symptoms could be brought on by medical conditions like seizures or alcoholic use problem, drug side effects, or mental diseases. The perception of hearing, smell, touch, vision, or physiological sensations may all be affected by hallucinations. A person may have hallucinations with or without knowledge that they are hallucinations. It is regarded as a psychotic sign when someone believes their delusion to be genuine.

A sphere of diameter 6.0cm is moulded into a thin uniform wire of diameter 0.2mm.calculate the length of the wire in metres.

Marta_Voda [28]

The length of the wire is 36 m.

The density is the ratio of the mass and volume of a substance. The density is given by the formula,

d=m/V

where d is the density. m is the mass and V is the volume.

The density of the material does not change and the initial and final volume of the substance will be equal when it has changed shape provided the mass has not been changed.

The radius r of the sphere is half of its diameter. Therefore, r=6.0/2 = 3.0 cm.

Then volume of the sphere Vs is given by the formula,

Vs=(4/3)*π*r^3

Put the value of r in the above formula.

Vs=(4/3)*3.14*(3.0)^3

Vs=113.04 cm^3

For the cylinder, the radius s=0.2/2 mm = 0.01 cm and the length l is unknown. The volume of the cylinder Vc is given by the formula,

Vc=πs^2l

Put s=0.01 cm in this equation and solve it.

Vc=(3.14)*(0.01)^2l

Vc=0.000314 l cm^2

The volume of the wire (cylindrical in shape) and the sphere are same, therefore,

Vc=Vs

0.000314 l =113.04

l=3600 cm

I=36 m.

Hence the length of the wire is 36 m.
