Answer:

The pumpkin's vertical displacement  is H=27.76m

The pumpkin's vertical velocity when it hits the ground is v=23.32m/s

Explanation:

x=v*t

9.5=4*t

t=2.38s

H=vi(t)+1/2at^2

H=1/2at^2

H=1/2(9.8)(2.38)^2=27.76

vf=vi+at

vf=2.38(9.8)

vf=23.32m/s

Answer:

The efficiency of the engine is 40 %

Explanation:

Given;

input energy, = 2500 J

output energy, = 1000 J

The efficiency of the engine is given as;

Efficiency = output energy / input energy

Efficiency = 1000 / 2500

Efficiency = 0.4

Efficiency(%) = 0.4 x 100%

Efficiency = 40 %

Therefore, the efficiency of the engine is 40 %

The efficiency of Engine is 40%.

Given data:

The amount of heat absorbed by gasoline engine is, Q = 2500 J.

The mechanical work performed by Engine is, W = 1000 J.

The tendency to do work is often rated and measured using the concept of efficiency of Engine. It is expressed as the ratio of work obtained and amount of heat supply. So, the expression for the efficiency of Engine is given as,

[tex]\eta = \dfrac{W}{Q}[/tex]

Solving as,

[tex]\eta = \dfrac{1000}{2500}\\\\\eta =0.4\\\\\eta = 0.4 \times 100\\\\\eta =40 \%[/tex]

Thus, we can conclude that the efficiency of Engine is 40%.

Explanation:

From the question we are told that

  The duty cycle is  p =  65% = 0.65

   The on - state voltage is  [tex]V = 40 \ volt[/tex]

Generally the average DC voltage is mathematically represented as

Answer:

the velocity of the water flow is 7.92 m/s

Explanation:

The computation of the velocity of the water flow is as follows

Here we use the Bernouli equation

As we know that

[tex]V_1 = \sqrt{2g(h_2 - h_1)}\\\\=\sqrt{2g(\Delta h)} \\\\= \sqrt{2\times9.8\times3.2} \\\\= \sqrt{62.72}[/tex]

= 7.92 m/s

Hence, the velocity of the water flow is 7.92 m/s

We simply applied the above formula so that the correct value could come

Answer:

a) 6.9*10^14 Hz

b) 9*10^-12 T

Explanation:

Given that

The wavelength of the wave, λ = 435 nm

Amplitude of the electric field, E(max) = 2.7*10^-3 V/m

a)

The frequency of the wave can be found by using the formula

c = fλ, where c = speed of light

f = c/λ

f = 3*10^8 / 435*10^-9

f = 6.90*10^14 Hz

b)

E(max) = B(max) * c, magnetic field amplitude, B(max) =

B(max) = E(max)/c

B(max) = 2.7*10^-3 / 3*10^8

B(max) = 9*10^-12 T

Answer:

The weight of this object is 8.45 N.

Explanation:

Given;

volume of the object, V = 7.5 x 10⁻⁴ m³

density of the object, ρ = 1.15 x 10³ kg/m³

The mass of the object is given as;

mass = density x volume

m = ρV

m = (1.15 x 10³)(7.5 x 10⁻⁴ )

m = 0.8625 kg

The weight of the object is given as;

w = mg

where;

g is acceleration due to gravity = 9.8 m/s²

w = 0.8625 x 9.8

w = 8.45 N

Therefore, the weight of this object is 8.45 N.

Answer:

IM SO SORRY :((

Explanation:

Answer:

875.59 N/m

Explanation:

From the question given above, the following data were obtained:

Force (F) = 10 lb

Extention (e) = 2 in

Spring constant (K) =?

Next, we shall convert 10 lb to Newton (N). This can be obtained as follow:

1 lb = 4.448 N

Therefore,

10 lb = 10 lb × 4.448 N / 1 lb

10 lb = 44.48 N

Thus, 10 lb is equivalent to 44.48 N

Next, we shall convert 2 in to metre (m). This can be obtained as follow:

1 in = 0.0254 m

Therefore,

2 in = 2 in × 0.0254 m / 1 in

2 in = 0.0508 m

Thus, 2 in is equivalent to 0.0508 m.

Finally, we shall determine the spring constant i.e the stiffness of the spring as follow:

Force (F) = 44.48 N

Extention (e) = 0.0508 m.

Spring constant (K) =?

F = Ke

44.48 = K × 0.0508

Divide both side by 0.0508

K = 44.48 / 0.0508

K = 875.59 N/m

Therefore the spring constant i.e the stiffness of the spring is 875.59 N/m

Answer:

The mass of first body is double, since mass is double.

This is due to momentum

The same net force is applied to two bodies. The first body acquires half of the acceleration of the second body. The mass of first body is double, since mass is double.

In Newtonian physics, an object's mass and velocity are combined to form momentum, more precisely linear momentum and translational momentum. It has both a magnitude as well as a trajectory, making it a vector quantity. If an item has a mass of m and a velocity of v (also a vector quantity).

The kilogram metre per second (kg m/s), or newton-second inside the International System of Units (SI), is the unit used to measure momentum. The same net force is applied to two bodies. The first body acquires half of the acceleration of the second body. The mass of first body is double, since mass is double.

Therefore, the mass of first body is double, since mass is double.

Answer:

The correct option is (a).

Explanation:

Given that,

Radius of a horizontal circle, r = 80 cm = 0.8 m

Angular velocity, ω = 5 rev/minute = 0.523 rad/s

We need to find the magnitude of its centripetal acceleration. The formula that is used to find the centripetal acceleration is given by :

[tex]a=\omega^2 r\\\\a=(0.523)^2\times 0.8\\\\a=0.218\ m/s^2[/tex]
