Being talked into volunteering in a homeless shelter is an example of negative peer pressure. Please select the best answer from

Viefleur [7K]

The statement ‘Being talked into volunteering in a homeless shelter is an example of negative peer pressure’ is false. Volunteering a homeless shelter is not an example of negative peer pressure, but rather, a positive peer pressure. Because your friends are helping you do something good that would not ruin your life.

. Assume you have a dot grid with 36 dots per sq.in. How many acres are represented by each dot using the following map scales:

elixir [45]

Answer:

a) 0.069 acres

b) 0.114acres

c) 17.78acres

Explanation:

1 dot=1/36sqin

a) 1 sqin= 330×330=108900ft^2

1 dot=108900/36 =3025ft^2

Converting to acre,divide by43560

3025/43560 =0.069acre

b) 1 chain =22 yards

25×22=550yards

Converting to acre divide by 4840

550/4840 =0.114acre

c)1 sqmile =640acres

(1/36) ÷ 640

640/36

17.78acres

4) Kinetic energy is directly related to _______

TEA [102]

Answer:

4) C.mass

5) C. Potential Energy

Explanation:

4) Kinetic energy (KE) of an object is the energy that it possesses due to its motion. If a mass is in motion ,it has a kinetic energy .

By definition

$Kinetic.Energy=\frac{1}{2}*mass*velocity^{2}$

what matters in Kinetic energy is the mass and the velocity only .

there fore the answer is

C.mass

5) Potential energy is the energy stored in an object, due to the object's position or arrangement.

By definition

$Potential.Energy=mass*gravitaional.Acceleration*height$

in potential energy the height matters.higher the height , higher the energy

therefore the answer is

C.Potential Energy

A box slides down a frictionless plane inclined at an angle θ ¸ above the horizontal. The gravitational force on the box is dire

DedPeter [7]

<h2>Answer: at an angle $\theta$ below the inclined plane. </h2>

If we draw the <u>Free Body Diagram</u> for this situation (figure attached), taking into account only the gravity force in this case, we will see the weight $W$ of the block, which is directly proportional to the gravity acceleration $g$ :
