Which tool would you use to measure the height of a cube of metal

Answers

Answer 1
Answer: It depends on the size of the cube, but you could use a ruler for almost any size, or if it is small enough, you could use a caliper to get a very precise measurement.
Answer 2
Answer: it really depends on the size.. if its huge i would use a meter ruler, if it is small use a reguler ruler...

An airplane is flying at a constant velocity through the air. What is the relationship between the magnitudes of the four forces shown in the diagram? A. L = W; F < D
B. L = W; F = D
C. L = W = F = D
D. L = W; F > D

Answers

Answer:

(B) L=W; F=D

Explanation:

Since the airplane's velocity is constant, the airplane is not accelerating in any direction. In absence of acceleration, all forces acting on the plane are balanced so that the net forces in the horizontal and the vertical directions are zero. Given the drawing, this implies that

Forward force = Drag force (F=D)

Weight = Lift (W=L)

which corresponds to option (B)

(it is not C because nothing in the text says that the vertical and horizontal components have to have same magnitude)

Final answer:

The relationship between the magnitudes of the forces is that lift force is equal to weight force, and drag force is equal to thrust force.

Explanation:

In this scenario, the airplane is flying at a constant velocity, which means that its acceleration is zero. According to Newton's first law of motion, if an object is moving with a constant velocity, the net force acting on it is zero.

Therefore, the relationship between the magnitudes of the four forces shown in the diagram is that the lift force (L) is equal to the weight force (W), and the drag force (D) is equal to the thrust force (F).

So, the correct answer is C. L = W = F = D.

Help with this question please.

Answers

There are 4 hydrogens on the right side (2\mathrm H_2=4\mathrm H), and 2 hydrogens on the left per molecule of \mathrm H_2. To get the same number of hydrogens on both sides, the coefficient should be 2.

(Then the number of oxygens will be consistent, since 2\mathrm H_2\mathrm O contributes 2 oxygens, and so does \mathrm O_2.)

Explain why atoms move at different speeds depending on whether they are in liquid or solids

Answers

Atoms move a lot faster in liquid because the molecules have more room to move freely. On the other hand, in a solid the molecules are very tight together, giving them little room to wiggle around.

A car traveling with constant speed travels 150 km in 7200 s. What is the speed of the car?Express the speed to two significant figures and include the appropriate units.

Answers

The speed of the car is 75 km/h

Further explanation

These are the formulas that we have to remember before solving the problem.

Speed is the rate of change of distance.

\large { \boxed {v = (d)/(t)}}

v = speed ( m/s )

d = distance ( m )

t = time ( s )

Acceleration is the rate of change of velocity.

\large { \boxed {a = (\Delta v)/(t)}}

a = acceleration ( m/s² )

Δv = change in speed ( m/s )

t = time ( s )

Let us now tackle the problem!

Given:

distance = d = 150 km

time taken = t = 7200 s = 2 hours

Unknown:

velocity = v = ?

Solution:

v = (d)/(t)

v = (150)/(2)

\large {\boxed {v = 75~km/h} }

The acceleration of the car is 0 m/s² because it travels with constant speed.

We could also plot the distance vs time graph as shown in the attachment.

Grade: Middle School

Subject: Physics

Chapter: Kinematics

Keywords: indycar top speed of a fastest police car has ever gone

Final answer:

The car's speed is 75 km/hour, as determined by dividing the total distance travelled (150 km) by the total time taken (2 hours).

Explanation:

To answer this question, we use the

formula for speed

, which is distance traveled divided by the time taken. Here, the distance travelled by the car is 150 km and the time taken is 7200 s (which is equal to 2 hours). Therefore, the speed will be 150 km divided by 2 hours, resulting in a speed of

75 km/hour

, stated to the correct number of significant figures.
