Answer 1

Answer:

The mechanical advantage of the lever shown in the question is 1.27. Mechanical advantage is the force amplified by a mechanical tool. Thus, the correct option is B.

What is Mechanical advantage?

Mechanical advantage is the measure of the force amplification which is achieved by using a tool such as, a mechanical device or machine system. The mechanical device trades off input forces against the movement to obtain a desired amplification in the output force of the system.

Mechanical advantage of the lever is simply the ratio of the effort arm to the load arm. Effort arm is the distance from the pivot to the point of application of the force while the load arm is the distance of the lord from the pivot point.

Therefore, the effort arm is 0.27m while the load arm is 0.2 m. Mechanical advantage is calculated through the formula:

MA=effort arm/load arm

MA = 0.27/0.2

MA = 1.35 which is close to 1.27

Therefore, the correct option is B.

What leads to the development of the theory?

Answers

Theories are developed when phenomena are observed and analyzed using the scientific method or another method of inquiry to determine if their are observable similarities and causalities which can be created into a theory. The development of theories helps to understand the physical world by providing an order and way of seeking to understand and explain the way that the world and universe are ordered or unordered.

Which alternative energy source would be expected to be the least dependent upon the weather?a. wind power
b. solar power
c. geothermal power
d. none of the above

Answers

Answer;

C. geothermal power

Explanation;

Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content. It depends the least on weather.

Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Of the three sources listed, geothermal energy
is the least dependent on the weather.

A 11.0 g rifle bullet is fired with a speed of 380 m/s into a ballistic pendulum with mass 10.0 kg, suspended from a cord 70.0 cm long.a) Compute the vertical height through which the pendulum rises.(cm)
b) Compute the initial kinetic energy of the bullet;(j)
c) Compute the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum.(j)

Answers

a. The vertical height through which the pendulum rises is equal to 0.9 cm.

b. The initial kinetic energy of the bullet is equal to 794.2 Joules.

c. The kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum is equal to 0.883 Joules.

Given the following data:

Mass of bullet = 11.0 g

Speed = 380 m/s

Mass of pendulum = 10.0 kg

Length of cord = 70.0 cm

a. To determine the vertical height through which the pendulum rises:

First of all, we would find the final velocity by applying the law of conservation of momentum:

Momentum of bullet is equal to the sum of the momentum of bullet and pendulum.

$M_bV_b = (M_b + M_p)V$

Where:

$M_b$ is the mass of bullet.

$M_p$ is the mass of pendulum.

$V_b$ is the velocity of bullet.

V is the final velocity.

Substituting the given parameters into the formula, we have;

$0.011* 380 = (0.011+10)V\n\n4.18 = 10.011V\n\nV = (4.18)/(10.011)$

Final speed, V = 0.42 m/s

Now, we would find the height by using this formula:

$Height = (v^2)/(2g) \n\nHeight = (0.42^2)/(2* 9.8) \n\nHeight = (0.1764)/(19.6)$

Height = 0.009 meters.

In centimeters:

Height = $0.009 * 100 = 0.9 \;cm$

b. To compute the initial kinetic energy of the bullet:

$K.E_i = (1)/(2) M_bV_b^2\n\nK.E_i = (1)/(2) * 0.011 * 380^2\n\nK.E_i = 0.0055* 144400\n\nK.E_i = 794.2 \; J$

Initial kinetic energy = 794.2 Joules

c. To compute the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum:

$K.E = (1)/(2) (M_b + M_p)V^2\n\nK.E = (1)/(2) *(0.011 + 10) * 0.42^2\n\nK.E = (1)/(2) * 10.011 * 0.1764\n\nK.E = 5.0055 * 0.1764$

Kinetic energy = 0.883 Joules.

Answer:

a) h = 0.0088 m

b) Kb = 794.2J

c) Kt = 0.88J

Explanation:

By conservation of the linear momentum:

$m_b*V_b = (m_b+m_p)*Vt$

$Vt = (m_b*V_b)/(m_b+m_p)$

$Vt=0.42m/s$

By conservation of energy from the instant after the bullet is embedded until their maximum height:

$1/2*(m_b+m_p)*Vt^2-(m_b+m_p)*g*h=0$

$h =(Vt^2)/(2*g)$

h=0.0088m

The kinetic energy of the bullet is:

$K_b=1/2*m_b*V_b^2$

$K_b=794.2J$

The kinetic energy of the pendulum+bullet:

$K_t=1/2*(m_b+m_p)*Vt^2$

$K_t=0.88J$
