Explanation:

Given parameters:

Density of silver = 10.5g/cm³

Volume of silver given = 4mL

Unknown:

Mass of silver = ?

Solution:

Density of a substance can be expressed as its mass per unit volume

Density = $\frac{mass}{volume}$

we need to convert our volume to cm³ from mL;

1cm³ = 1mL

So 4mL = 4cm³

input the values in;

Mass = density x volume = 10.5 x 4 = 42g

Imagine a moving boat making waves in the middle of a pool of water. Also, imagine two observers, one behind the boat and one in

Simora [160]

The person who is behind the boat will see much powerful and bigger waves than the person who is in front of the boat. This phenomenon is caused by the Doppler effect which describes the changes in the observed frequency of a wave whenever there is relative motion between the wave source and the observer.

What evidence do you need to determine that two rocks have some similar minerals because the minerals from the original rock was

klio [65]

Answer:

It comes from same parent material.

Explanation:

The two rocks have some similar minerals which indicates that they are comes from the same parent material but with the passage of time it is mixed with other minerals due to which they are some different in composition from one another so we can conclude that they comes from the same parent material due to the presence of some similar minerals.

Naoki's bicycle has a mass of 10 kg. If Naoki sits on her bicycle and starts pedaling with a force of 168 N, causing an accelera

White raven [17]

Answer:

50 kg

Explanation:

Data:

Mass of bicycle = 10 kg

F = 168 N

a = 2.8 m/s²

Calculation:

F = ma Divide each side by m, Then

m = F/a

= 168/2.8

= 60 kg

m = mass of bicycle + Naoki's mass. Then

60 = 10 + Naoki's mass Subtract 10 from each side

Naoki's mass = 50 kg

A gas at 400 k is placed in a 4.0 l moveable piston. The gas is cooled to 252 k. What is the new volume of the piston?

katrin [286]

Answer:

2.52L

Explanation:

Given parameters:

T₁ = 400K

V₁ = 4L

T₂ = 252K

unknown

V₂ = ?

Solution:

To solve this problem, we are going to apply charle's law. The law states that the volume of a fixed mass of gas is directly proportional to temperature provided pressure is constant.

Mathematically,

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

Substitute and solve for V₂

$\frac{4}{400} = \frac{V_{2} }{252}$

V₂ = 2.52L
