An atom of Cu-63 has 34 neutrons and an atom of Cu-65 has 36 neutrons. 27- The total number of electrons in an atom of Cu-65 is 29 because copper has atomic number of 29, which simply means that an atom of copper has 29 protons and 29 electrons.

Explanation:

Answer:

Copper-65 has 36 neutrons, 29 electrons and 29 protons

Explanation:

Answer:

When two materials are rubbed together, the material with the greatest affinity for electrons is the material which takes electrons away from the other material. Saran wrap takes electrons from nylon and acquires the negative charge. In turn, the nylon loses electrons and becomes charged positively.

1. The distance of image from the plane mirror is same as the distance of object (person) from the plane mirror but the image is formed behind the mirror.

v=u=3 m

Thus distance between image and the person d=u+v=3+3=6 m

2.A concave mirror has a radius of curvature of 1.0 m. An object is placed 2.0 m in front of the mirror. Can you determine the location of the image (in cm)

1/v = 1/f - 1/u = 1/50 - 1/200 = 4/200 - 1/200 = 3/200

v = 200/3 c

Answer:

PE = 13734 Joules

Step-by-step explanation:

Formula: PE = m * g * h

Givens

m = 40000 grams

m = 40000 grams * 1kg/1000 grams = 40 kg

g = 9.81

h = 35 m

PE = 40 * 9.81 * 35

PE = 13734 Joules

Answer:

Distance for which the balloon has been pulled by the child = 12 meter

Force applied by the child to pull the balloon = 1.0 Newton

The angle below horizontal = 60 degree

These information's are already given in the question. Based on the above information's the answer to the question can be easily determined.

We know that

Work done = Force * Distance * Cos(60)

                  = 1 * 12 * (1/2)

                  = 1 * 6

                  = 6 Joules

So the work done by the child is 6 joules. I hope the procedure is clear enough for you to understand. Based on the above mentioned procedure, you can always solve problems of similar kind without taking any outside help.

The maximum height of the ball if A ball is launched at 5.5 m/s at 76 degrees above the horizontal is 1.45 meters.

Distance, regardless of the direction of the travel, is the entire path that an object in motion has taken. Since the direction of motion is ignored while measuring distance, it is referred to as a scalar quantity. There is only one possible value for the distance: positive.

Given:

A ball is launched at 5.5 m/s at 76 degrees above the horizontal, It starts and lands at the same distance from the ground,

Calculate the maximum height as shown below,

Maximum height = [tex]v^2sin^2a / 2g[/tex]

Maximum height = 5.5² × sin²76° / 2 × 9.8

Maximum height = 30.25 × 0.97² / 19.6

Maximum height = 30.25 × 0.9409 / 19.6

Maximum height = 28.46 / 19.6

Maximum height = 1.45 m

Thus, the maximum height is 1.45 meters.

The reaction force is the force that counterbalances the weight of the roof and acts upwards.

The question is incomplete but I will try to help you the much I can. The image of the house is not shown hence the free body diagram can not be produced.

However, let me explain to you that force is a vector hence it has direction. The total resultant force is obtained by taking the direction of all the forces into account and this is called resolution of the forces. The reaction force is the force that counterbalances the weight of the roof and acts upwards.

The total distance you would have covered is equivalent to going around the earth 22 times.

The total distance traveled at a given speed and time of motion is calculated as follows;

Distance = speed x time

[tex]Distance = \frac{25 \ miles}{day} \times \frac{365 \ days}{1 \ year} \times 60 \ years\\\\Distance = 547, 500 \ miles[/tex]

The distance round the earth or circumference of the earth of the earth has been given as 25,000 miles

[tex]n = \frac{547,500}{25,000} \\\\ n = 21.9 \ times \ \approx 22 \ times[/tex]

Thus, the total distance you would have covered is equivalent to going around the earth 22 times.

Answer:

140km/hr

Explanation:

This is a simple converstion.

We know that the bus travels 350km/150min.

We want to know the speed in km/h. All we need to know is that per 1 hr there are 60 min.

350km/150min * 60min/1hr  (we want to make sure that the value we are trying to eliminate, in this case the minute, is on the opposing side.)

(350*60)/150 = 21,000km/150hr

let's simplify to only per 1 hr.

21000/150 = 140

150/150 = 1

Therefore, the speed of the bus is 140km/hr

A bus travels a total of 350 km in 150 minutes, so the average speed of the bus in km/hr will be 140 km/hr.

The object's average speed is how far it travels overall in a predetermined amount of time. The scalar quantity represents the average speed. It has no direction; instead, magnitude is used to describe it.

Average Speed =  [tex]Total \ Distance/Total\ time[/tex]

An indicator of a vector is average velocity. Average velocity is calculated by dividing the change in position or displacement by the intervals during which it occurs. The average velocity may be positive or negative depending on how the displacement is dispersed. The standard international unit of average velocity is meters per second (m/s).

Average Velocity = [tex]Total \ Displacement/Total \ Time[/tex]

According to the question, the given values are :

Distance, d = 350 km

Time, t = 150 minutes or

t = 2.5 hours.

Average Speed = 350/2.5

Average speed = 140 km/hr

Hence, the average speed of the bus will be 140 km/hr.
