B. Give explanations for natural events
C. Make predictions
D. Produce unchanging, absolute answers

Answers

What is not the ultimate goal of science is to produce unchanging and absolute answers - D. Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions. And it isn't really the case that they would like to produce unchanging answers.

A 75 force is applied to the side of a crate resting on a level floor. The crate has a mass of 25kg. If the coefficient of static friction is .15, is the 75 N force enough to make the crate accelerate? Explain why or why not.

Answers

If the coefficient of static friction is 0.15, then 0.15 of the crate's weight
shows up as a force resisting the horizontal pull. So we really only
need to know the crate's weight.

Weight = (mass) x (gravity) = (25) x (9.8) = 245 newtons.

0.15 of 245 newtons = 36.75 newtons.

The force due to friction that's holding the crate back, not letting it start
sliding, is 36.75 newtons. If you push it with 75 newtons of force, then
that IS enough to make the crate accelerate.

A 1200 kg vehicle initially travelling at 50. km/h experiences an air resistance of 5000 N and road friction of 2200 N. The wheels deliver a force of 7500 N to the vehicle. What is its acceleration?

Answers

The forces on the car are:
-- 7,500 N forward, from the engine
-- 5,000 N backwards, from air resistance
-- 2,200 N backwards, from road friction

The net force on the car is (+7,500 - 5,000 - 2,200) = 300 N forward .

Newton said: Force = (mass) x (acceleration)
Divide each side by (mass) :
Acceleration = (force) / (mass)

Acceleration = (300 N) / (1,200 kg) = 0.25 m/s² forward.

Notice the big red herring at the beginning of the question:
It's nice to know that the vehicle starts out traveling at 50 km/hr,
but in order to answer this question, we honestly don't care !

An alarm clock draws 0.5 A of current when connected to a 120 volt circuit. Calculate its resistance.

Answers

We need to calculate the resistance of a clock which draws current I=0.5A and is connected to a circuit of V=120V. We can find the resistance of a circuit from Ohm's law: I=U/R where I is the current, U is the voltage and R is the resistance. So lets manipulate Ohm's law to find the resistance: R=U/I. Now we input our numbers: R=120V/0.5A and we get R=240 Ohm. So the resistance is R=240 Ohm.

Given the amount of voltage and the amount of current drawn by the alarm clock, its resistance is 240 ohms.

What is Ohm’s law?

Ohm’s law states that "the potential difference between two points is directly proportional to the current flowing through the resistance.

It is expressed as;

V = I × R

Where V is the voltage or potential difference, potential difference, I is the current and R is the resistance.

Given the data in the question;

Voltage V = 120V

Current I = 0.5A

Resistance R = ?

We substitute our given values into the expression above.

V = I × R

120V = 0.5A × R

R = 120V / 0.5A

R = 240Ω

Therefore, given the amount of voltage and the amount of current drawn by the alarm clock, its resistance is 240 ohms.

While skiing, Ellen encounters a ledge that sends her flying horizontally at a rate of 12 m/s. How far away will she land if the ledge is 7 meters high? ...?

Answers

In this problem, we must first calculate that Ellen will be on air. Using the equation of a free-falling body,

y = -g/2*t^2 + y0

When she hits the ground, y = 0. With y0 = 7 and g = 9.80,
0 = -4.90*t^2 + 7
t = 1.20 s

Thus, her horizontal displacement is then
x = vt
x = (12)(1.20)
x = 14.3 m

Your friend won the race that you were both running. Instead of being gracious, your friend made fun of you for losing, and now you don't want to run anymore. What is this an example of? Positive peer pressure Negative peer pressure Positive peer influence Negative peer influence

Answers

Answer: Option (d) is the correct answer.

Explanation:

When my friend made fun of me for loosing the race then obviously this thing left me with no confidence. Also, I would feel shame for losing.

As a result, i have decided not to run anymore.

This represents an example of negative peer influence as the comments or fun made by my friend has made me come to a negative decision.
