. A 5 kg turkey and a 3.5 kg turkey are suspended on opposite sides of a single pulley.
zavuch27 [327]

Answer:

a) 40.3725 N

b) a=1.729 m/s^2

Explanation:

mass of turkey 1 M= 5 kg

mass of turkey 2 m= 3.5 kg

Let T be the tension in the string and a be the acceleration of the system

then from FBD in the attachment

T-mg=ma.................1

Mg-T=Ma..................2

from 1 and 2 we find a as

a= \frac{Mg-mg}{M+m}

now substituting the values we get

a= \frac{5g-3.5g}{5+3.5}

a= \frac{1.5g}{8.5}

a=1.729 m/s^2

now from equation 1 we can calculate Tension T as

T-mg=ma

T= m(a+g)

T= 3.5(1.729+9.81)= 40.3725 N

How do you find the missing terms in a number sentence?
FrozenT [24]

Determine the rule that the numbers in the sequence obey, and then utilize this rule to determine the missing term to complete a number sequence. The rule that the numbers in the example above adhere to is "Add 8 and then remove 2." Therefore, 32 is the term that is missing from the given number sequence.

<h3>What is a number sentence?</h3>
  • A number sentence is an equation or inequality that is articulated using numbers and mathematical symbols in the context of mathematics education.
  • In the US, Canada, UK, Australia, New Zealand, South Africa, and other countries, the phrase is used in the instruction of elementary-level mathematics.
  • The word is employed when asking pupils to write equations using fundamental mathematical symbols.
  • Unknown values are sometimes denoted by boxes or forms.
  • To introduce pupils to the ideas of structure and basic algebra before more formal teaching of these concepts, number sentences are utilized.
<h3>A math sentence is what?</h3>
  • A mathematical statement about two expressions is made.
  • Either integers, variables, or a combination of both are used in the two phrases.
  • Additionally, words or symbols like equals, greater than, or less than can be used in a mathematical phrase.

In a playground, there is a small merry-go-round of radius 1.20 m and mass 160 kg. Its radius of gyration is 91.0 cm. (Radius of
aksik [14]

Answer:

a) 145.6kgm^2

b) 158.4kg-m^2/s

c) 0.76rads/s

Explanation:

Complete qestion: a) the rotational inertia of the merry-go-round about its axis of rotation 

(b) the magnitude of the angular momentum of the child, while running, about the axis of rotation of the merry-go-round and

(c) the angular speed of the merry-go-round and child after the child has jumped on.

a) From I = MK^2

I = (160Kg)(0.91m)^2

I = 145.6kgm^2

b) The magnitude of the angular momentum is given by:

L= r × p The raduis and momentum are perpendicular.

L = r × mc

L = (1.20m)(44.0kg)(3.0m/s)

L = 158.4kg-m^2/s

c) The total moment of inertia comprises of the merry- go - round and the child. the angular speed is given by:

L = Iw

158.4kgm^2/s = [145kgm^2 + ( 44.0kg)(1.20)^2]

w = 158.6/208.96

w = 0.76rad/s

If displacement covered by a particle is zero then distance cover by it<br>​
sleet_krkn [62]

Answer:

When displacement is zero, the particle may be at rest, therefore, distance travelled = 0.

Again, when displacement is zero, the final position matches with the initial position after some time, but the distance travelled will not be zero.
