assuming that the styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat capacity of the metal, cmcmc m ? express your answer numerically in joules per kilogram kelvin.

Answers

Answer 1

The specific heat capacity of the metal, cm is 214.87 J/kg-k.

As per the given data,

we need to find  the specific heat capacity of the metal, cm.

According to the above question,

it is given that,

Weight of  chunk of an unknown metal is 1.00kg

chunk has been in boiling water for several minutes and it is quickly dropped into an insulating Styrofoam beaker containing 1.00kg of water at 18.0°C.

After stirring for 5.00 minutes, the water's temperature has reached a constant value of 22.0°C .

The water specific heat capacity  is cw = 4190J/(kg)  

Now,

temperature of metal is 100 degree celsius ( water boils at 100 degree celsius )

equilibrium temperature = 22 degree celsius

specific heat capacity of water Cw= 4190 J/kg-K

According to question, specific heat capacity of metal be Cm

Therefore,

mass of metal that is Mm = 1 kg

mass of water that is Mw = 1 kg

we know that,

heat energy lost by metal is equal to  heat energy gained by water

(assuming no heat is lost to the surroundings)

heat energy lost by metal = Mm * Cm * (100 - 22)

heat energy lost by water = Mw * Cw * (22 - 18 ) (given - initial temperature of water = 18 degree celsius)

therefore,

Mw * Cw * (22 - 18 ) = Mm * Cm * (100 - 22)

4190 * 4 = Cm * 78

Cm = 214.87 J/kg-k

Hence, the specific heat capacity of the metal, cm is 214.87 J/kg-k.

A golf ball is hit upward at an angle from the horizontal and speed v=40m|s.it reaches a maximum height of 10m as illustrated above.assume the ballistic trajectory starts from ground level and ignore air resistance..assume the shot is made on a wide level field...
What is the initial angle?

Answers

Answer:

Explanation: v = 40 m/s, H = 10m, g = 9.8 m/s2

H = (v * sinθ)^2 / 2g

H = v^2 * (sinθ)^2 / 2g

H = (40)^2 * (sinθ)^2 / 2g

H = 1600 *  (sinθ)^2 / 2g

Cross multiply

2gH = 1600 * (sinθ)^2

2 * 9.8 * 10 = 1600 * (sinθ)^2

196 = 1600 * (sinθ)^2

Make (sinθ)^2 the subject of the formula

(sinθ)^2 = 196 / 1600

Take the square root of both sides

√(sinθ)^2 = √( 196 / 1600)

sinθ = 0.35

θ = sin^-1(0.35)

θ = 20.48731511

Approx. 20.49

Cyclotron to make 1 milligram of the isotope fluorine-18 for use a a diagnostic tool with it PET scanner. It seems that the hospital should plan to make more F-18 the next morning, as the amount remaining at midnight is very small.

The half-life of F-18 is 1.8 hours, so after 1.8 hours, half of the original amount of F-18 will remain. After 3.6 hours, a quarter of the original amount will remain, and so on.

At 3:00 PM (9 hours after the F-18 was made), the hospital will have

At midnight (18 hours after the F-18 was made), the hospital will have

an athlete pushes a 50-kg sled with a horizontal force of 200 n and it fails to move. what is the net force on the sled?

Answers

The net force on the sled is 400 N.

The net force on the sled is the sum of all the forces acting on the sled. In this case, the only forces acting on the sled are the horizontal force of 200 N applied by the athlete and the force of friction acting on the sled.

The force of friction is given by the equation:

F_friction = μ × F_normal

where F_friction is the force of friction, μ is the coefficient of friction between the sled and the surface it is on, and F_normal is the normal force acting on the sled.

The normal force is the force exerted on an object by a surface that is perpendicular to the surface. For an object at rest, the normal force is equal to the weight of the object. In this case, the weight of the sled is 50 kg × 9.8 m/s² = 490 N.

Plugging the values for the coefficient of friction, the normal force, and the applied force into the equation gives us the following:

F_friction = μ × F_normal = μ × 490 N = 200 N

The net force on the sled is the sum of the horizontal force applied by the athlete and the force of friction:

F_net = F_horizontal + F_friction = 200 N + 200 N = 400 N

Therefore, the net force on the sled is 400 N.

what is the distance from eart's center to a point outside earth's center where the gravitational acceleration a due to earth is 1/10 of its value from surface

Answers

The distance of point where gravitational acceleration a due to earth is 1/10 of its value from surface is  7436.8km.

We know that value of acceleration due to gravity at surface of earth is given by the formula g=GM/r²

where G is the earth's gravitational constant, M is the mass of earth and r is the distance between center and surface of earth.

Now,when we consider a point outside the surface of earth as h then value of acceleration due to gravity is =GM / (r+h)²

Now,we are given that value of acceleration due to gravity is 1/10 to the value at surface

∴GM / (r+h)²=(1/10) × (GM/r²)

=>r²/(r+h)² = 1/10

=>r/(r+h)=  √(1/10)

=>r/(r+h)= 1/√10

On further solving,we get

=>√10 ×r=r+h

=>r×(√10-1)=h

Since this point is from center of earth and we need to find point from surface,there distance of point is =h-r=r×(√10-1)-r=r×(√10-2)=1.162r

Now,we know that radius of earth is 6400km

So,on putting =1.162r=1.162×6400=7436.8Km

Hence,distance of point from surface of earth is 7436.8km.

The horizontal component of the boat's velocity is the velocity of the boat along the horizontal direction or x - axis of the boat's motion.

The magnitude of the horizontal component of the boat's velocity is calculated as follows;

Vx = V cos (θ)

where;

V is the speed of the boatθ is the direction of the boat's speed

Vx = 50 m/s  x  cos (35)

Vx = 40.96 m/s

Thus, the horizontal component of the boat's velocity is a function of the initial velocity and the direction of the velocity.

an object is moving to the right with speed vi when a force of magnitude f is exerted on it. in which of the following situations is the object’s direction of motion changing and kinetic energy decreasing at the instant shown?

Answers

The situation that is the object’s direction of motion changing and kinetic energy decreasing at the instant shown in diagram A.

What is kinetic energy?

The energy that a body possesses as a result of its motion is known as kinetic energy. A body with kinetic energy must thus be in motion. Remember that a force is what causes motion.

Now, a force must act in the same direction as the moving object in order to enhance its kinetic energy. As a result, the diagram presented in option A should be the appropriate response to the question.

Therefore, the correct option is A.

The question is incomplete. Your most probably complete question is given below: the image is added.

a student had two balls labeled 1 and 2. the balls were identical in size. she applied the same force on both the balls and assumed that the balls would undergo similar acceleration. however, she found that ball 2 traveled a greater distance while in the air. the student concluded that ball 2 had less mass than ball 1, which caused it to accelerate and move faster.which scientific concept did the student most likely use to arrive at this conclusion?

Answers

The scientific concept that the student most likely used to arrive at his conclusion is Newton's laws of motion.

Newton's Laws of motion - Newton's Laws of motion consists of 3 important Laws. The three laws of motion help us understand how objects behave when standing still, when moving and when forces act upon them.

according to Newton's 2nd laws:

F = ma (where m is mass and a is acceleration of the object)

the subject applied same force on both the balls, but the ball 2 travelled greater distance.

F = M1a1

M1 = F/a1

and M2 = F/a2

and S = 1/2at2 if initial velocity is 0.

so, S is directly proportional to a

so, M1 = F/S1

and M2 = F/S2

Since, S2 is greater than S1, so M2 is less than M1 because distance is inversely proportional to mass of the object.

Assume the following waves are propagating in air

a) Calculate the wavelength lambda_1 for gamma rays offrequency f_1 = 6.30×1021 Hz.

c) Calculate the wavelength lambda_2 for visible light offrequency f_2 = 5.40×1014 Hz.

Answers

A. The wavelength of light in gamma ray is 4.76x10⁻¹³m.

B. The wavelength of light in the visible light range is 5.55x10⁻6m.

The wavelength of the light ray is always given by

Lambda=c/f, where c is the speed of light in vacuum and it's value is c=3x10⁹ m/sec and f is the frequency of the light ray.

a. The frequency of the gamma-ray (f1)=6.3x10²¹ Hertz. Since , lambda =c/f , Lambda 1=c/f1 =(3x10⁹)  / (6.3x10²¹) =4.76x10⁻¹³ m.

The normal wavelength of the gamma rays are always below 100 pm or 10⁻¹⁰ m.

b.The frequency of visible light (f2) =5.40x10¹⁴ Hertz.  Lambda 2=c/ f2  =(3x10⁹) / (5.40x10¹⁴) =5.55x10⁻⁶ m.The normal range of wavelength of visible light is 400-700 nm.
