Answer:

blank space can determine any quantity

Explanation:

a blank works so that people can determine amounts or rules that best suit their preferences or situations, as is the example of an amount of money that is lent in a bank, banks already have made loan contracts, With the space of the white quantity, this for reasons of saving time and having an already legalized agreement that can be applied to any of its customers, then in that space they put the desired amount, the same happens with a certain type of sales, it is also used to set rules

Each croquet ball in a set has a mass of 0.53 kg. The green ball, traveling at 14.4 m/s, strikes the blue ball, which is at rest

faust18 [17]

a) 14.4 m/s

The problem can be solved by using the law of conservation of total momentum; in fact, the total initial momentum must be equal to the final total momentum:

$p_i = p_f$

So we have:

$m_g u_g + m_b u_b = m_g v_g + m_b v_b$ (1)

where

$m_b = m_g = m = 0.53 kg$ is the mass of each ball

$u_g = 14.4 m/s$ is the initial velocity of the green ball

$u_b = 0$ is the initial velocity of the blue ball

$v_g=0$ is the final velocity of the green ball

$v_b$ is the final velocity of the blue ball

Simplifying the mass in the equation and solving for $v_b$ , we find

$v_b = u_g = 14.4 m/s$

b) 12.0 m/s

This time, the green ball continues moving after the collision at

$v_g = 2.4 m/s$

So the equation (1) becomes

$u_g = v_g + v_b$

And solving for $v_b$ we find

$v_b = u_g - v_g = 14.4 m/s-2.4 m/s=12.0 m/s$

c) 13.5 m/s

This time, the green ball continues moving after the collision at

$v_g = 0.9 m/s$

So the equation (1) becomes

$u_g = v_g + v_b$

And solving for $v_b$ we find

$v_b = u_g - v_g = 14.4 m/s-0.9 m/s=13.5 m/s$

10) Um viajante, ao desembarcar no aeroporto de Londres, observou que o valor da temperatura do ambiente na escala Fahrenheit é

joja [24]

Answer:

The observed temperature was 10º Celsius or 50º Fahrenheit.

Explanation:

The traveler observed that the temperature in Fahrenheit is five times the value of the temperature in Celsius, therefore:

$F = 5*C$

A Fahrenheit temperature relates to a Celsius one by the following expression:

$F = \frac{9}{5}*C + 32$

Using the second expression on the first, we can solve for the temperature in Celsius, this is done below:

$\frac{9}{5}*C + 32 = 5*C\\\frac{9}{5}*C - 5*C = -32\\\frac{9*C - 25*C}{5} = -32\\\frac{-16*C}{5} = -32\\-16*C = -32*5\\-16*C = -160\\C = \frac{-160}{-16} = 10\º\text{C}\\F = 5*C = 5*10 = 50\º\text{F}$

The observed temperature was 10º Celsius or 50º Fahrenheit.

A car experiences a centripetal acceleration of 4.4 m/s ^2 as ur rounds a corner with a speed of 15 m/s. What is the radius of t

damaskus [11]

The calculation of the centripetal acceleration of an object following a circular path is based on the equation,

a = v² / r

where a is the acceleration, v is the velocity, and r is the radius.

Substituting the known values from the given above,

4.4 m/s² = (15 m/s)² / r

The value of r from the equation is 51.14 m.

Answer: 51.14 m

If an organism starts from only one cell,how do we get different body parts and organs

Vladimir [108]

Every cell has chromosomes in its nucleus. In a human cell,
there are 26 of them. AND ... lined up on every chromosome
are thousands and thousands of GENES. Those carry the
instructions for what kind of organ or bone or tissue or hair
this cell will be used to build, how the structure will work, how
tall you will be, what color your eyes will be, how deep your
voice will be, and what illnesses you will have.

Every cell has the complete set of instructions in it. In the past
several years, we have just started to be able to read them, and
extraordinary progress has been made. There's an awful long way
still left to go.

A bike rider approaches a hill with a speed of 8.5 m/s. The total mass of the bike rider is 91kg. What is the kinetic energy of

Anestetic [448]

a) The kinetic energy (KE) of an object is expressed as the product of half of the mass (m) of the object and the square of its velocity (v²):

$KE = \frac{1}{2}m* v^{2}$

It is given:

v = 8.5 m/s

m = 91 kg

So:

$KE= \frac{1}{2}*91*8.5^{2} =3,287.4J$

b) We can calculate height by using the formula for potential energy (PE):
PE = m*g*h

In this case, h is eight, and PE is the same as KE:
PE = KE = 3,287.4 J

m = 91 kg

g = 9.81 m/s² - gravitational acceleration

h = ? - height

Now, let's replace those:

3,287.4= 91 * 9.81 * h

⇒ h = 3,287.4/(91*9.81) = 3,287.4/892.7 = 3.7 m
