Hello again :)

The answer is A.  because the electrons are <em>always</em> located outside of the nucleus, and you can see that they are negatively charged.

Hope I helped :)

A golf ball is struck at 75 m/s at an angle of 60 degrees. What is the
Gnesinka [82]

Answer:

v_x=37.50

Explanation:

The rectangular components of a vector \vec v having a magnitude v and angle θ are:

v_x=v\cos\theta

v_y=v\sin\theta

The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.

The variables of the equations have the values:

v = 75 m/s

θ = 60°

Substituting into the formula:

v_x=75\cos 60^\circ

v_x=75\cdot 0.5

v_x=37.5~m/s

Without specifying units and with precision to the hundredths place:

\mathbf{v_x=37.50}

A copper wire has a radius of 2.9 mm. When forces of a certain equal magnitude but opposite directions are applied to the ends o
REY [17]

Answer:

550000000N/m

Explanation:

Given that a copper wire has a radius of 2.9 mm. When forces of a certain equal magnitude but opposite directions are applied to the ends of the wire, the wire stretches by 5.0×10−3 of its original length.

Original length L = 0.005L

the strain = extension/ original length

the strain = 0.005L / L

the strain = 0.005

Young modulus = stress / strain

11 × 10^10 = stress / 0.005

Cross multiply

Stress = 11 × 10^10 × 0.005

Stress = 550 000000 N/m

Therefore, the tensile stress on the wire is 550000000 N/m.

Two cars start from rest at a red stop light. when the light turns green, both cars accelerate forward. the blue car accelerates
irinina [24]
<span>19 m/s
   This is an exercise in ignoring unneeded data. We want to know how fast the blue car is going after 3.6 seconds. The acceleration is 5.2 m/s^2 for 4.5 seconds. Since 4.5 is greater than 3.6, we know the car was under constant acceleration of 5.2 m/s^2 for the entire 3.6 seconds. So we just need to multiply to get the answer. 3.6 s * 5.2 m/s^2 = 18.72 m/s
   Since we only have 2 significant figures in our data, we need to round to 2 significant digits, giving 19 m/s</span>

Given two objects of the same mass but of different sizes, which object has a greater density?
wolverine [178]

Given two objects of the same mass but of different sizes, the one that has a greater density is: a. the smaller object

Due to the density of an object is the relation that exist between the mass and the space that the object occupies, if we have two objects with the same mass the one that is going to have a greater density is the smaller object because it occupies less space with more mass.  

We can prove it using the density formula to solve the following exercise:

Two objects have a mass of  100 g, and their volume are 20 cm³ and 10 cm³ respectively, what is the density of each one?

The general formula of the density is:

d = m/v

Where:

  • d= density
  • m= mass
  • v= volume

Information about the problem:

  • m = 100 g
  • v1= 20 cm³
  • v2=10 cm³
  • d1=?
  • d2?

Applying the density  formula we get:

d = m/v

d1 = 100g/20 cm³

d1 = 5g/cm³

d2 = 100g/10 cm³

d2 = 10g/cm³

With the results we can confirm that the object that has the greater density is the smaller, because it has less volume.

<h3>What is density?</h3>

It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.
