Verdah, Hetav and Dhinesh are undertaking an investigation into the motion of wooden blocks in their Physics class. Their aim is to determine the effect that mass has on the horizontal motion of the wooden block across a table.
Verdah suggests that they use a launcher to give both blocks the same initial velocity and that they use the same table for each trial.

The blocks are made from the same wood but have different masses. The mass of block A (m1) is twice the mass of block B (m2). The coefficient of friction between the blocks and the table is u.

Alvin and Theodore race across a parking lot 451 cm long. Alvin travels at 19.28 cm/s and Theodore at 12 cm/s. When the Alvin crosses the finish line, how far behind is Theodore?

Answers

Theodore is 170 centimeters from the finish line when Alvin crosses it.

The total distance is 451 cm, so we can find the time that takes Alvin to crosses the finish line as follows:

[tex] v_{a} = \frac{x}{t} [/tex]   (1)

Where:

[tex] v_{a}[/tex]: is the speed of Alvin = 19.28 cm/s

x: is the total distance = 451 cm

t: is the time that takes Alvin to crosses the finish line =?

By solving equation (1) for t, we have:

[tex]t = \frac{x}{v} = \frac{451 cm}{19.28 cm/s} = 23.4 s[/tex]

Now, after 23.4 seconds have elapsed, Theorode has traveled the following distance ([tex]x_{t}[/tex]):

[tex] x_{t} = v_{t}*t [/tex]

Where:

[tex]v_{t}[/tex]: is the speed of Theodore = 12 cm/s  

[tex] x_{t} = v_{t}*t = 12 cm/s*23.4 s = 281 cm [/tex]

The distance (d) that Theodore needs to travel to cross the finish line is:

[tex]d = x - x_{t} = 451 cm - 281 cm = 170 cm[/tex]

Therefore, Theodore is 170 centimeters from the finish line when Alvin crosses it.

What is the current across the secondary coil? A 2.5 A C 250 A B D 5.0 A 500 A​

Answers

Answer:

A

Explanation:

Wattage = E * I

E = 25

I = 5

Wattage = 25 * 5

Wattage = 125

The secondary, in an ideal transformer has the same wattage.

125 = 50 * I           Divide by 50

Explanation:

A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?​

Answers

Answer:

[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]

Explanation:

We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.

[tex]F= \ m \times a[/tex]

1. Calculate Acceleration

The mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.

[tex]a= \frac{v_f-v_i}{t}[/tex]

The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).

[tex]v_f=[/tex]10 m/s [tex]v_i=[/tex]0 m/s t= 5 s

Substitute these values into the formula.

[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]

Divide.

[tex]a= 2 \ m/s/s[/tex]

[tex]a= 2 \ m/s^2[/tex]

2. Calculate Force

Now we know the mass and acceleration of the wheelbarrow

m= 20 kg a= 2 m/s²

Substitute the values into the force formula.

[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]

[tex]F= 40 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.

[tex]F= 40 \ N[/tex]

Answer:

40 N

Explanation:

We know that

F = ma

and

a = (v - u)/t

So,

F = m(v - u)/t

F = 20(10 - 0)/5

F = 20(10/5)

F = 20(2)

F = 40 N

Define acceleration. Prove that v = u + at​

Answers

Explanation:

[tex]\text{Acceration is the rate of change of velocity per unit time.}

\text{Suppose the initial velocity is }u,\text{ and the final velocity is }v.

\text{Then the change of speed is }v-u.

\text{If such velocity change takes }t\text{ seconds, the average acceleration is }a.

\text{So we write}[/tex]

[tex]\frac{v-u}{t}=a\implies v=u+at[/tex]

There are 60 seconds in 1 minute. So, 3 minutes is the same as 3×60=180 seconds. If you travel 6 m/s (meaning after 1 second, you've run 6 meters), then after 3 minutes (or 180 seconds), you have run 6×180=1080 meters.

Answer: I think the vertical acceleration values are not equal to the theoretical acceleration due to gravity, -9.81 meters/second2 due to the gravity force and maybe the drag due to air resistance.

Explanation: About my earlier prediction about which ball will land first, I can say that my hypothesis was right, but not quite because I calculated the average vertical acceleration, where the time period is t = 0.10 second to t = 1.00 second, the results were different. If the result were maybe right or close to the I would have said that my hypothesis was correct.

can someone help me convert these?

Answers

Assuming you are supposed to write each conversion in scientific notation:

(2) 1 m = 100 cm, so

(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m

(3) 1 km = 1,000 m, so

(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m

(4) 1 m = 1,000 mm = 10³ mm, so

(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm

(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so

(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m

(6) 1 g = 1,000,000 µg = 10⁶ µg, so

(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g
