A vehicle is traveling at a speed of 92.5 km/h. What is this value in feet per second? Note that, by definition, 1 in = 2.54 cm.
Harlamova29_29 [7]

Answer:

v=84.3\frac{ft}{s}

Explanation:

Hello,

In this case, given that 1 kilometer equals 1000 meters, 1 meter equals 3.281 feet and 1 hour equals 3600 seconds, the required velocity in feet per second turns out:

v=92.5\frac{km}{h}*\frac{1000m}{1km}  *\frac{3.281ft}{1m} *\frac{1h}{3600s}\\ \\v=84.3\frac{ft}{s}

Regards.

At the center of every atom lies a small, dense ____________ that is positively charged
Sedbober [7]
At the center of every atom lies a small, dense "nucleus" that is positively charged.

Atom is the smallest unit of matter. It is made up of electrons, protons and neutrons. Electrons are negatively charged particles that are found scattered in different energy levels outside the nucleus. Protons are positively charged particles present inside the nucleus. Neutrons do not carry charge and found inside the nucleus. Thus, protons and neutrons make up the nucleus of an atom. Since, protons are positively charged and neutrons are uncharged particles, the charge of nucleus becomes positive.

Butter has a specific gravity of 0.86. What is the mass of 2.45 L<br> of butter?
Tema [17]

Answer:

mass of the butter is 2.107 kg

Explanation:

specific gravity = destiny of the substance / density of

the water at 4°C

0.86 = density of the butter / 1000

where density of the water is 1000 kg/m^3 at 4°C

density of the butter = 860kg/m^3

now,

density of the butter = mass of the butter / volume

860 = mass of the butter / 2.45 × 10^-3

( 1 L = 10^ -3 m^3)

mass of the butter = 2.107 kg
