Answer:

The net and only force acting on the ball thrown up into the air at half of its maximum height is the weight  of the ball

Explanation:

When the ball is rising in the air, the force, F, acting on it is given by the product of the mass, m × acceleration, a

The acceleration of a body thrown in the air = Gravitational acceleration = g = Constant

Therefore;

The force acting on the body thrown in the air F = Constant = m × g (downwards)

The force acting on the ball thrown up into the air at half of its maximum height = The mass of the ball × The acceleration due to gravity = The weight  of the ball.

Answer:

62.5m

Explanation:

Given parameters:

Acceleration  = 5m/s²

Unknown:

Distance traveled by car  = ?

Solution:

To solve this problem, we use one of the motion equations as given below:

     S  = ut + [tex]\frac{1}{2}[/tex] at²

S is the distance traveled

t is the time taken

u is the initial velocity  = 0m/s

a is the acceleration

Now insert the parameters and solve;

      S = (0 x 5) + ([tex]\frac{1}{2}[/tex] x 5 x 5²) = 62.5m

Answer: 1.1x10^21 photons / sec

Explanation:energy per photon

.. E / photon = hc / L = (6.626x10^-34 J x sec) x (3.00x10^8 m/sec) / (6.5x10^-6m)

.. E / photon = 3.06x10^-20 J / photon

then

.. (32.7 watts) x (1 J/sec / 1watt) x (1 photon / 3.06x10^-20J) = 1.1x10^21 photons / sec

The number of photons are emitted per second will be "1.07".

According to the question,

Power,

           = 32.8 J/s

Wave length,

          = [tex]6.5\times 10^{-6}[/tex]

As we know,

→ [tex]E = \frac{hc}{\lambda}[/tex]

By substituting the values, we get

      [tex]= \frac{32.8}{\frac{(4.42\times 10^{-34})(3\times 10^{-4})}{4.5\times 10^{-6}} }[/tex]

      [tex]= \frac{32.8}{3.055e}[/tex]

      [tex]= 1.07[/tex]

Given

[tex]u = 0[/tex] -- Initial Velocity

[tex]a = 5.0m/s^2[/tex] --- acceleration

[tex]t =5.0s[/tex] -- time

Calculate the distance

This question will be solved using the following equation of motion

[tex]S = ut + \frac{1}{2}at^2[/tex]

Where S represents the distance

Substitute values for u, t and a

[tex]S = 0 * 5.0 + \frac{1}{2} * 5.0 * 5.0^2[/tex]

[tex]S = 0 + \frac{1}{2} * 5.0 * 25.0[/tex]

Answer:

Time Saved = 0.374 h = 22.4 min

Explanation:

First we calculate the time required at old speed limit:

s = v₁t₁

where,

s = distance from Portland to Bangor = 215 km

v₁ = old speed limit = 88.5 km/h

t₁ = time taken with old speed limit = ?

Therefore,

215 km = 88.5 km/h (t₁)

t₁ = (215 km)/(88.5 km/h)

t₁ = 2.429 h

Now, we calculate the time taken at the new speed limit:

s = v₂t₂

where,

s = distance from Portland to Bangor = 215 km

v₂ = new speed limit = 104.6 km/h

t₂ = time taken with new speed limit = ?

Therefore,

215 km = 104.6 km/h (t₂)

t₂ = (215 km)/(104.6 km/h)

t₂ = 2.055 h

So, the time saved will be:

Time Saved = t₁ - t₂ = 2.429 h - 2.055 h

Time Saved = 0.374 h = 22.4 min

Question:

The flow of air caused by _____ and the Coriolis effect creates distinct _____ on Earth's surface.

Answer:

Explanation:

The flow of air caused by variations in the rate at which the different parts are heated up as well as the Coriolis effect combine to create distinct wind patterns on Earth's surface.

The Coriolis Effect is used to describe a "force" that causes things (like objects, planes, air currents) traveling long distances around the Earth to appear to bend as they move rather than in a straight line.

Answer:

3.77202

Explanation:81.9 kg×9.8N/kg÷0.0021 Pa ×(1atm/101325)=3.77202

The pressure exerted between her toes and the ground is 3.77 atm.

The stress at a location within a confined fluid or the perpendicular force per unit area are the two definitions of pressure used in the physical sciences. A 42-pound box with an area of 84 square inches at the bottom will apply pressure on a surface equal to the force divided by the surface area.

Given:

An 81.9 kg person stands on her toes. The surface area of her toes in contact with the ground is only 0.00210 m²,

Calculate the pressure on the toe as shown below,

The pressure on the toe = Force of man / area of toe

The pressure on the toe = mass of man × 9.8 / 0.00210

The pressure on the toe = 81.9 × 9.8 / 0.00210

The pressure on the toe = 802.62 / 0.00210

The pressure on the toe = 382200 N/m²

The pressure on the toe = 382200 / 101325 (1 atm = 101325 N / m²)

The pressure on the toe = 3.77 atm,

Explanation:

Answer:

The velocity of motion at which the occupants of the car appear to weigh 20% less than their normal weight is approximately 19.81 m/s

Explanation:

The given parameters are;

The curvature of the hill, r = 200 m

Due to the velocity, v, the occupants weight = 20% less than the normal weight

The outward force of an object due to centripetal (motion) force is given by the following equation;

[tex]F_c = \dfrac{m \times v^2}{r}[/tex]

Where;

r = The radius of curvature of the hill = 200 m

Given that the weight of the occupants, W = m × g, we have;

[tex]F_c = 0.2 \times W = 0.2 \times m \times g[/tex]

[tex]\therefore 0.2 \times m \times g = \dfrac{m \times v^2}{r}[/tex]

v = √(0.2 × g × r)

By substitution, we have;

v = √(0.2 × 9.81 × 200) ≈ 19.81

The velocity of motion at which the occupants of the car appear to weigh 20% less than their normal weight ≈ 19.81 m/s.

The velocity is 19.81 m/sec at which the occupants of the car appear to weigh 20% less than their normal weight and this can be determined by using the formula of centripetal force.

Given :

A car is going over the top of a hill whose curvature approximates a circle of radius 200 m.

The centripetal force acting on the car is given by the formula:

[tex]\rm F_c = \dfrac{mv^2}{r}[/tex]   ---- (1)

where m is the mass of a car, v is the velocity of the car and r is the radius of curvature.

Now, it is given that the occupants of the car appear to weigh 20% less than their normal weight that means:

[tex]\rm F_c = 0.2\times W[/tex]

[tex]\rm F_c = 0.2 \times m \times g[/tex]   --- (2)

Now, equate equation (1) with equation (2).

[tex]\rm \dfrac{mv^2}{r}=0.2\times m \times g}{}[/tex]

[tex]\rm v = \sqrt{0.2\times g \times r }[/tex]

[tex]\rm v = \sqrt{0.2\times 9.81 \times 200 }[/tex]

v = 19.81 m/sec

The velocity is 19.81 m/sec at which the occupants of the car appear to weigh 20% less than their normal weight.
