When bitten by an animal, one should:

Keep the animal under observation for 14 days

Stay under observation for a doctor for 14 days

Wait for symptoms to develop

Consider rabies injections if the animal is not found

Please hurry!

Answer:

0.1m/s²

Explanation:

Using the equation of motion

V = u+at

V is the final speed = 0.9m/s

Initial speed u = 0.5m/s

Time = 4secs

Get the acceleration

0.9 = 0 5+4a

0.9-0.5 = 4a

0.4 = 4a

a = 0.4/4

a = 0.1m/s²

Hence the acceleration is 0.1m/s²

Answer:

140

Answer:

skateboard mid-ollie is being actively steered. This is exactly what makes doing an ollie so hard. It's not enough to get the skateboard up into the air - you also have to steer it while it's in the air. You should keep your hands up in the hair a bit to help with balance, scrunch your legs a bit down to have a proper and effective jump. wear nee pads incase you dont fix the landing. Practice jumping on ur skate board tho, if u jump at it without knowing much youll just get hurt.

Answer:

  [tex]\frac{Y}{Y_o}[/tex] = 2/3

Explanation:

The yuong modulus of a rod is defined as the relationship between the tensile strength and the strain

         Y =  [tex]\frac{ \frac{F}{A} }{\frac{\Delta L}{L_o} }[/tex]

let's use the subscript "o" for rod A

         I = [tex]\frac{ \frac{F}{A_o} }{ \frac{\Delta L}{L_o} }[/tex]

tells us that rod B has

         A = 3 A₀

         L = 2 L₀

we substitute

         Y = [tex]\frac{ \frac{F}{A} }{ \frac{\Delta L}{L} }[/tex]

          Y = [tex]\frac{ \frac{F}{3A_o} }{ \frac{\Delta L}{ 2L_o} }[/tex]

         y = ⅔  [tex]\frac{ \frac{F}{A_o}}{ \frac{\Delta }{L_o} }[/tex]

substituting the value of Y₀

          Y = ⅔  Y₀

           [tex]\frac{Y}{Y_o}[/tex] = 2/3

Answer:

the speed of the waves is 150 cm/s

Explanation:

Given;

frequency of the wave, f = 10 Hz = 10

distance between 4 nodes, L = 15.0 cm

The wavelength (λ) of the wave is calculated as follows;

Node to Node = λ/2

L = 2(Node to Node) = (4 Nodes) = 2 (λ/2) = λ

Thus, λ = L = 15.0 cm

The speed (v) of the wave is calculated as follows;

v = fλ

v =  10 Hz   x  15.0 cm

v = 150 cm/s

Therefore, the speed of the waves is 150 cm/s

Answer:

Hooke's law can be written as:

F = -k*Δx

Where k is a constant that depends on the spring, called the spring constant.

And Δx = (x - x₀) is the displacement of the spring with respect to the rest position x₀

And a proportional equation is something like:

y = c*x

Where c is a constant of proportionality.

In the case of Hooke's law, the constant is K, then the force is proportional to the displacement of the spring with respect to the rest position Δx.

Answer:

Resistance is inversely proportional to the cross section area of the material, hence when cross sectional area is tripled, also resistance triples.

Since heat is caused due to resistance, also heat current triples.

Answer:

a) The work done by the force is 720 joules, b) The power supplied by the force is 138 watts.

Explanation:

a) Since force is uniform and parallel to the direction of motion, the work ([tex]W[/tex]), in joules, done by the force ([tex]F[/tex]), in newtons, is defined by this formula:

[tex]W = F\cdot s[/tex] (1)

Where [tex]s[/tex] is the travelled distance, in meters.

If we know that [tex]F = 60\,N[/tex] and [tex]s = 12\,m[/tex], then the work done by the force is:

[tex]W = F\cdot s[/tex]

[tex]W = (60\,N)\cdot (12\,m)[/tex]

[tex]W = 720\,J[/tex]

The work done by the force is 720 joules.

b) And an expression for the power supplied by the force ([tex]\dot W[/tex]), in watts, is concieved by differentiating (1) in time:

[tex]\dot W = F\cdot \dot s[/tex]

Where [tex]\dot s[/tex] is the speed of the wagon, in meters per second.

If we know that [tex]F = 60\,N[/tex] and [tex]\dot s = 2.3\,\frac{m}{s}[/tex], then the power supplied by the force is:

[tex]\dot W = F\cdot \dot s[/tex]

[tex]\dot W = (60\,N)\cdot \left(2.3\,\frac{m}{s} \right)[/tex]

[tex]\dot W = 138\,W[/tex]

The power supplied by the force is 138 watts.

Answer:

 #_electrons = 2 10¹⁰ electrons

Explanation:

For this exercise we can use a direct rule of three proportions rule. If an electron has a charge of 1.6 10⁻¹⁹ C how many electrons have a charge of 3.2 10⁻⁹ C

          #_electrons = 3.2 10⁻⁹ ( [tex]\frac{1}{1.6 \ 10^{-19}}[/tex])

          #_electrons = 2 10¹⁰ electrons

Answer:

The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.

Answer:

X-ray Telescope

Explanation:

X-ray Telescope which can be either hard or soft is an instrument on an orbiting satellite that would detect the flare first.

This is because X-ray Telescope is technically designed to detect and determine X-rays or radio and optical emissions from flares, from places or points beyond Earth's atmosphere.

Answer:

the impulse experienced by this object is 4 Ns

Explanation:

Given;

mass of the object, m = 3 kg

velocity of the object, v = 4 m/s

resistive force, F = 20 N

duration of impact, t = 0.2 s

The impulse experienced by this object is calculated as follows;

J = F x t

J = 20 x 0.2

J = 4 Ns

Therefore, the impulse experienced by this object is 4 Ns

Answer:

60N

Explanation:

force = mass * acceleration

force = 12 * 5

force =60N
