The time it takes the baton to complete one spin is determined as 0.56 s.

The time of motion of the baton is calculated as follows;

a = 4π²R/T²

where;

T² = 4π²R/a

T²  = (4π² x 0.38)/47.8

T²  = 0.3138

T = 0.56 s

Thus, the time it takes the baton to complete one spin is determined as 0.56 s.

See below ~

Explanation:

A decrease in the ice caps causes a(n) increase in the absorption of sunlight. This cause the global temperature to rise causing more ice caps to melt. As more ice caps melt, the temperature rises. This is an example of a negative feedback loop.

The radius of the circle in which the plane is flying is 1887 m.

The aerodynamic lift is the force that keeps the aircraft flying in the air.

Let the  aerodynamic lift be F1 sinθ= mv^2/R ---- (1)

and F1 cosθ= mg --------- (2)

Equating (1) and (2) and eliminating the mass;

R = v^2/ g tanθ

Where v = 490 km/h or 136 m/s

R = (136)^2/9.8 * tan 45

R = 18496/ 9.8

R = 1887 m

I would hit it as hard as you can with the club.

Explanation:

well one thing that I like to do is hit the golf ball as hard as possible with the club.

This is because for me, when I do that, I can normally get more momentum which means I also get a farther hit.

The minimum amount of heat needed to melt it to a liquid will be 569.067 kJ.

The minimum amount of heat needed to melt it to a liquid is known as the enthalpy of fusion.

The formula for the enthalpy of the fusion is;

[tex]\rm L_f=Q/m \\\\ L_f=mCdt/m \\\\ L_f= Cdt \\\\ L_f= 899 J/kg^0C \times (660^0-27^0) \\\\ L_f= 569,067 \ J \\\\\ L_f=569.067 \ kJ[/tex]

Hence, the minimum amount of heat needed to melt it to a liquid will be 569.067 kJ.

Second choice

Explanation:

I suppose ME is the same as POTENTIAL energy

ME = mgh =  70 * 10 * 12 = 8400j

  Half way down,   4200 j is converted to Kinetic Energy

       1/2 m v^2 = 4200

       1/2 (70)  v^2 = 4200       v = 10.95 m/s

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

An oscillator makes 720 vibrations in 3 minutes. so, we have to solve the given problems based on it ~

#1. what's the number of vibrations per minute •

[tex]\qquad \sf  \dashrightarrow \: 3 \: min = 720 \: vib[/tex]

[tex]\qquad \sf  \dashrightarrow \: 1 \: min = \dfrac{720}{3} [/tex]

[tex]\qquad \sf  \dashrightarrow \: 1 \: min = 240 \: vib[/tex]

#2. Calculate unit vibrations per second •

[tex]\qquad \sf  \dashrightarrow \: 1 \: min = 240 \: vib[/tex]

[tex]\qquad \sf  \dashrightarrow \: 60 \: sec = 240 \: vib[/tex]

[tex]\qquad \sf  \dashrightarrow \: 1 \: sec = 4 \: vib[/tex]

#3. What's it's time period •

time taken to do 1 vibration is known as a period, so we can infer that :

[tex]\qquad \sf  \dashrightarrow \: 1 \: vib = \dfrac{1}{4} \: sec[/tex]

[tex]\qquad \sf  \dashrightarrow \: t = 0.25 \: sec[/tex]

#4. what is it's frequency in hert •

[tex]\qquad \sf  \dashrightarrow \: f = \dfrac{1}{t} [/tex]

[tex]\qquad \sf  \dashrightarrow \: f = \dfrac{1}{0.25} [/tex]

[tex]\qquad \sf  \dashrightarrow \: f = 4 \: hertz[/tex]

Answer:

0.1667Hz

Explanation:

by explanation frequency is given by 1/time

after carrying out the calculation of time we can easily get frequency.

time=speed/distance

=18/3

=6s

but frequency=1/time

hence=1/6

Surface Tension

The strong surface tension enables the paper clip float on the water, despite its much higher density which is caused by the cohesive forces between liquid molecules.

(a)The required speed for take off will be 24.49 m/sec.

(b)The minimum length must the runway have 193 m.

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its SI unit is m/sec.

(a)The required speed for take off will be 24.49 m/sec.

From the Newtons third equation of motion;

[tex]\rm v^2 = u^2+2as \\\\ v=0+2 \times 2 \times 150 \\\\ v=\sqrt{600}\\\\ v=24.49 \ m/sec[/tex]

Hence, the required speed for take off will be 24.49 m/sec.

(b)The minimum length must the runway have 193 m.

From the Newtons third equation of motion;

[tex]\rm v^2 = u^2+2as \\\\ (27.78)^2 = 0+2\times 2 s \\\\\ s=192.93 \ m[/tex]

Hence, the minimum length must the runway have 193 m.
