Answer:

5m/s is the answer s=d/t 25/5=5m/s

Answer:

5m/s

Explanation:

The formula for speed is s=distance/time. The distance traveled was 25 meters. The time it took to travel that distance was 5 seconds. Therefore, s= 25m/5s to give an answer of 5 m/s

Answer:

(a) Cyclist A travels faster.

(b) The time taken by cyclists A and B is 10 minutes and 8.58 minutes respectively.

Explanation:

Given that the speed of cyclist A= 24 km/h

As 1 km = 1000 m and 1 hour= 3600 seconds.

So, [tex]24 \frac {km}{h}=24\times \frac{1000 m}{3600 s}=\frac{20}{3}\frac {m}{s}=6.67 m/s[/tex]

and the speed of cyclist B = 6.8 m/s.

The length of the road = 4 km=4000 m.

(a) Speed of cyclist A is 6.67 m/s which is more than the 6.8 m/s.

Hence, cyclist A travels faster.

(b) If d be the distance to be traveled and V be the speed, than the time, t, required is,

[tex]t=\frac{d}{V}\cdots(i)[/tex]

For cyclist A:

As A is located at the beginning of the road, he has to cover full length of the road.

So, the distance to be covered by cyclist A =4 km.

Hence, from equation (i), the time taken by cyclist A is

[tex]t=\frac{4}{24}=\frac{1}{6}[/tex] hour

[tex]=\frac{1}{6}\times {60}=10[/tex] minutes. [ as 1 hour = 60 minumes]

So, time taken by cyclist A is 10 minutes.

For cyclist B:

As B is located 500 meters later from the beginning of the road, he has to cover the remaining length of the road.

So, the distance to be covered by cyclist B =4000 m-500 m= 3500 m.

Hence, from equation (i), the time taken by cyclist B is

[tex]t=\frac{3500}{6.8}=514.71[/tex] seconds

As 60 seconds= 1 minute.

So, t= 514.71/60 minutes = 8.58 minutes.

[tex]=\frac{1}{6}\times {60}=10[/tex] minutes. [ as 1 hour = 60 minumes]

So, the time taken by cyclist B is 8.58 minutes.

Answer:

force=1250kg * 30m/s+10

Explanation: it's a change in acceleration

Answer:

q₂ = 3.81 x 10⁻⁸ C = 38.1 nC

q₁ = 7.63 x 10⁻⁸ C = 76.3 nC

Explanation:

The force between two charges is given by Coulomb's:

F = kq₁q₂/r²

where,

F = Force = 0.00081 N

k = Coulomb's Constant = 9 x 10⁹ Nm²/C²

q₁ = magnitude of 1st charge

q₂ = magnitude of second charge

r = distance between charges = 18 cm = 0.18 m

Therefore,

0.00081 N = (9 x 10⁹ Nm²/C²)q₁q₂/(0.18 m)²

q₁q₂ = (0.00081 N)(0.18 m)²/(9 x 10⁹ Nm²/C²)

q₁q₂ = 2.916 x 10⁻¹⁵ C²

q₁ = 2.916 x 10⁻¹⁵ C²/q₂   --------------- equation (1)

It is given that:

q₁ = 2q₂   --------------- equation (2)

Comparing equation (1) and equation (2):

2q₂ = 2.916 x 10⁻¹⁵ C²/q₂

q₂² = 2.916 x 10⁻¹⁵ C²/2

q₂ = √14.58 x 10⁻¹⁶ C²

q₂ = 3.81 x 10⁻⁸ C = 38.1 nC

using this value in equation (2):

q₁= 2(3.81 x 10⁻⁸ C)

q₁ = 7.63 x 10⁻⁸ C = 76.3 nC

Initial speed of the coin (u)= 0 (As the coin is released from rest)

Acceleration due to gravity (a) = g = 9.81 m/s²

Time of fall (t) = 1.5 s

From equation of motion we have:

[tex] \boxed{ \bf{v = u + at}}[/tex]

By substituting values in the equation, we get:

[tex] \longrightarrow [/tex] v = 0 + 9.81 × 1.5

[tex] \longrightarrow [/tex] v = 14.715 m/s

[tex] \therefore [/tex] Speed of the coin as it hits the ground/Final speed of the coin = 14.715 m/s

The speed of the coin as it hits the ground is 14.715 m/s.

We can solve the problem above using the equation of acceleration under gravity.

⇒ Equation:

v = u+gt................... Equation 1

⇒ Where:

From the question,

⇒ Given:

Substitute these values into equation 1

Note the speed has a negative sign because it acts in the same direction as the acceleration due to gravity

Hence, the speed of the coin as it hits the ground is 14.715 m/s.

Answer:

1.5g/cm³

Explanation:

Given parameters:

Initial volume of the liquid  = 30cm³

Final volume of the liquid  = 50cm³

Mass of the liquid  = 30g

Unknown:

Density of the liquid  = ?

Solution:

Density is the mass per unit volume of a substance.

  Density  = [tex]\frac{mass}{volume}[/tex]  

volume of the liquid  = final volume - initial volume  =  50cm³  -  30cm³

 volume of the liquid  = 20cm³

Density  = [tex]\frac{30}{20}[/tex]   = 1.5g/cm³

I think there's a typo in the question...

Vertically, the box is in equilibrium, so its weight and the normal force (magnitudes w and n, respectively) are such that

n + (-w) = 0

The box has mass 70 kg, and assuming gravitational acceleration with magnitude g = 9.80 m/s², it has a weight of

w = (70 kg) g = 686 N

and hence

n = 686 N

Horizontally, the box is accelerated 3.0 m/s², so the net force acting on it is

∑ F = (70 kg) (3.0 m/s²) = 210 N

and the only forces acting in this dimension are the pulling force with magnitude 130 N and the friction force with magnitude f so that

130 N - f = 210 N

The friction force is proportional to the normal force by a factor of µ, the coefficient of kinetic friction, so that

f = µ n

and so we have

130 N - µ (686 N) = 210 N   →   µ ≈ -0.117

but µ can't be negative!

The problem is that the pulling force should have a magnitude larger than that of the net force, so either the given mass, acceleration, or pulling force are incorrect.
