10 turns of wire are closely wound around a pencil as shown in the figure. when measured using a scale as shown, the length of total turns is obtained 25mm. then a) What is the thickness of the wire? b) Express the thickness of the wire in centimetre.
please write correct answer
Answer:
a. The thickness of the wire is 2.5 mm.
b. The wire is 0.25 cm thick.
Explanation:
Number of turns of the wire = 10
The length of total turns = 25 mm
a. The thickness of the wire can be determined by;
thickness of the wire = [tex]\frac{length of total turns}{number of turns}[/tex]
= [tex]\frac{25}{10}[/tex]
= 2.5 mm
Therefore, the wire is 2.5 mm thick.
b. To determine the thickness of the wire in centimetre;
10 mm = 1 cm
So that,
2.5 mm = x
x = [tex]\frac{2.5}{10}[/tex]
= 0.25 cm
The wire is 0.25 cm thick.
The momentum of an object is determined to be 7.2 x 10-3 cm kg x m/s. Express this as provided or use any equivalent unit. How is this expressed in value and units?
Complete Question:
The momentum of an object is determined to be 7.2 × 10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g).
Answer:
7.2 gm/s.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
Given the following data;
Momentum = 7.2 * 10^-3 kgm/s
1 kg = 1000 g
Substituting the unit in kilograms with grams, we have;
Momentum = 7.2 * 10^-3 * 1000 gm/s
Momentum = 7.2 gm/s.

A car of mass 800 kg goes round a corner of radius 65 m at a
speed of 10 m/s.
a) What size force is needed to achieve this?
b) Suggest how this force is likely to be obtained.
c) What force would be needed if the driver approached the
bend at twice the speed?
Answer:
a. Centrifugal force = 1230.77 Newton.
b. Centrifugal force = mv²/r
c. Centrifugal force = 4923.08 Newton.
Explanation:
Given the following data;
Mass = 800kg
Radius = 65m
Velocity = 10m/s
a. To find the force;
Centrifugal force = (800*10²)/65
Centrifugal force = (800*100)/65
Centrifugal force = 80000/65
Centrifugal force = 1230.77 Newton.
b. The force associated with the car is generally referred to as centrifugal force because it's the force required to keep the car in a curved or circular path. It can be calculated using the formula;
Centrifugal force = mv²/r
c. To find the force at twice the speed;
Velocity = 2 * 10 = 20m/s
Centrifugal force = (800*20²)/65
Centrifugal force = (800*400)/65
Centrifugal force = 320000/65
Centrifugal force = 4923.08 Newton.
a. To achieve a car of mass 800 kg goes round a corner of radius 65 m at a speed of 10 m/s , needed 1230.77 Newton centripetal forces.
b. When an object goes round a corner then centripetal forces keep that object moving in a curved path.
c. When speed is twice. then, 4923.07 Newton centripetal forces needed.
a. Given that car of mass 800 kg goes round a corner of radius 65 m at a
speed of 10 m/s.
Centripetal force ,[tex]F=\frac{mv^{2} }{r}[/tex]
Where m is mass, v is speed of object and r is radius.
Substituting all values in above equation.
[tex]F=\frac{800*10^{2} }{65} =1230.77Newton[/tex]
b. Centripetal force is defined as, the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.
As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion.
c. When speed is twice, then [tex]v=10*2=20m/s[/tex]
Centripetal force,[tex]F=\frac{800*20^{2} }{65} =4923.08Newton[/tex]

What is electric field?The field developed when a charge is moved. In this field, a charge experiences an electrostatic force of attraction or repulsion depending on the nature of charge.
Given, the electric field 1.22 m from charge is 1570 N/C, pointing
toward the charge.
The electric field and charge is related as
E = kq/r²
q = Er²/k
where k = 9 x 10⁹ N.m²/C²

A football player kicked a ball at an angle of 37o above the horizontal with an initial velocity of 20 m/s, what is the maximum height reached by the ball? a. 62 m b. 26 m c. 7.4 m d. 5.1 m
Answer:
H = 8.45 m
Explanation:
Given that,
Angle of projection, [tex]\theta=37^{\circ}[/tex]
The initial velocity of the ball, u = 20 m/s
We need to find the maximum height reached by the ball. The formula for the maximum height is given by :
[tex]H=\dfrac{u^2\sin^2\theta}{2g}\\\\H=\dfrac{(20)^2\times \sin^2(37)}{2\times 9.8}\\\\H=8.45\ m[/tex]
So, the maximum height reached by the ball is 8.45 m.

Lengthen the moment/time of impact
Bend knees right before impact
Spread out arms and legs to slow down
Shorten the length/time of impact
Answer:
Momentum is equal to mass for velocity (p1=mv)
But momentum is also equal to Force for time of impact (p1=Ft). Hence the impact force is inversely proportional to the fall time and directly proportional to the mass and fall velocity : F=mv/t^2 or F=p1/t
If he slows down, v diminishes and F diminishes
Hence correct Answer is C

Xander goes airborne on his scooter as he exits a half-pipe at Newton's Skate Park. Xander and his scooter have a total mass of 50 kg. The net force acting on Xander and the scooter is 25N. What is Xander's acceleration?
Hello,
QUESTION)According to the 2nd Newton's law,
✔ We have : F = m x a ⇔ a = F/m; with F in N, m in kg, a in m/s²
a = 25/50a =0.5 m/s²Therefore Xander's acceleration is 0.5 m/s².
The total mass of Xander and his scooter is 50 kg and the net force acted due to Xander and his scooter is 25 N then the acceleration will be 0.5 m/s².
What is Acceleration?Acceleration is the rate at which the speed and orientation of a moving object change over time. When a spot or object moves faster or slower along a straight line, it is said to be accelerated. Even though the speed is constant, motion on a circle accelerates so because the direction is always shifting. Both by and to acceleration for all other types of motion.
It is a vector quantity because it has both magnitude and direction.
As per the given information provided by the question,
Mass, m = 50 kg
Force, F = 25 N
F = ma
25 N = 50 × a
a = 25/50
a = 0.5 m/s².
Therefore, the acceleration of Xander's acceleration will be 0.5 m/s²

A burst of sound takes 0.4 seconds to reach the seabed and return, if speed of sound in water is 1400m/s. what is the depth of water?
Explanation:
Given:
Speed of sound = 1400 m/s
Total time taken = 0.4 seconds
To find:
The depth of water
Solution:
As it take 0.4 seconds for the burst to reach the seabed and return (both ways), we can deduce that it takes 0.2 seconds to reach the seabed (one way).
This is because the speed of sound is a constant.
Now, to find the depth, we use the equation
Speed = Distance/Time
Here, we know the values of speed (1400 m/s) and time (0.2 seconds). Distance is the depth of the water, which we need to find. Let the distance be x.
Therefore
1400 = x/0.2
x = 1400 * 0.2
x = 280 m
We get the depth as 280 metres.

1. As you get ready for bed, you roll up one of your socks into a tight ball and toss it into the laundry
basket across the room. Then, you try to toss the other sock without rolling it up.. What effects whether
or not your socks land in the basket?
Answer:
When you toss a rolled up sock across the room, it travels faster as it becomes round and has more weight added on it and this causes the sock to travel in the direction you wish and this gives you a high chance of the sock going straight into the laundry basket, no matter how far away you are.
On the other hand, throwing a sock without rolling it up will cause the sock to just flat down as you throw it. It will travel at a low speed because it has no weight on it since it is flat, and if you try to throw it, it will atleast land 21 cm away from you. About a 0% chance of it getting in the basket.
