Answer:

B. A dish of water is placed in the freezer and turns solid

Explanation:

it is a physical change because it can return to its original state by physical means. the other options are chemical changes because things like color change, bubbles or fizzing, and odor change all indicate a chemical change and cannot return to the original state it was in before.

Answer:

Water

Explanation:

Answer:

So, water has a specific heat of exactly 1.00 calorie per gram per °C. Because one calorie is equal to 4.18 J, it takes 4.18 J to raise the temperature of one gram of water by 1°C. In joules, water's specific heat is 4.18 J per gram per °C.

The answer is water.

Answer:

Answer:

t = 7 seconds

Explanation:

Given that,

The acceleration of a car, a = 4 m/s²

The initial velocity of the car, u = 0

Final velocity of the car, v = 28 m/s

We need to find how much time the car to reach a speed of 28 m/s. Using the definition of the acceleration of a car. It is given by :

[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{28}{4}\\\\t=7\ s[/tex]

So, it will take 7 seconds to reach a speed of 28 m/s.

Answer:

C. Mg3N2

Explanation:

Magnesium has a positive 2 charge and nitrogen has a negative 3 charge. To completely balance it out, you need three magnesium’s and two nitrogen’s. The final charge for magnesium would be positive 6 and the final charge for nitrogen would be negative 6, this will make it neutral.

Answer:

C. Mg3N2

Answer:

    m v ´- MV = (m + M) v ’

Explanation:

If the astronaut initially has a speed v the satellite has a speed V, we can define a system that is formed by the two bodies, therefore the forces during the collision are internal, so the momentum is conserved

initial instant. Before the crash

          p₀ = m v - MV

final instatne. After the crash, we have two cases

1) inelastic shock

          m_f = (m + M) v '

          p₀ = p_f

         m v ´- MV = (m + M) v ’

2) elastic collision with the astronaut's velocity, zero in this case the moment remains

        m v - MV = mv ’+ Mv’

also the kinetic energy is conserved

       mv'2 + M V2 = mv'2 + m v'2

with these two equations we can find the speed of the cars

Answer:

1) The force Christian can exert on his bicycle before picking up the the cargo is 529.74 N

2) The force Christian can exert on his bicycle after picking up the the cargo is 647.46 N

Therefore, Christian has to exert more force on his bike after picking up the cargo

Explanation:

The given parameters are;

The mass of Christian and his bicycle = 54 kg

The mass of the cargo = 12 kg

1) The force Christian can exert on his bicycle before picking up the the cargo = Mass of Christian and his bicycle × Acceleration due to gravity

∴ The force Christian can exert on his bicycle before picking up the the cargo = 54 kg × 9.81 m/s² = 529.74 N

2) The force Christian can exert on his bicycle after picking up the the cargo = (54 + 12) kg × 9.81 m/s² = 647.46 N

Therefore, Christian has to exert more force on his bike after picking up the cargo.

hello some parts of your question is missing attached below is the missing part

Answer :

a) 360 m

b) 120 m  ( eastward )

c) -120 m ( westward )

d) 80 m  ( eastward )

Explanation:

given data:

Each leg time = 1 minute

Total time = 3 minutes

t=0        t= 2            t = 3             t = 1

xo =0     x2 = 40     x3 = 120       x1 = 160

a) Distance travelled by skier in first 3 minutes

d = | x1 - xo | + | x2 - x1 | + | x3 - x2 |

    = 160 + 120 + 80 = 360 m

b) net displacement in first 3 minutes

s = ( x1 -x0 ) + ( x2 - x1 ) + ( x3 -x2 )

  = 120 m  ( eastward )

c) displacement during the second minute

s1 = x2 - x1  = 40 - 160  = -120 m ( westward )

d) displacement during the third minute

s2 = x3 - x2 = 120 - 40 = 80 m  ( eastward )

(a) The distance traveled by the skier in the first 3 minutes is 360.

(b) The displacement of the skier during the second minute is 120 west.

(c) The displacement of the skier during the third minute is 80 east.

The given parameters;

The distance traveled by the skier in the first 3 minutes is calculated as follows;

[tex]x = (120 - 40) + 120 + 160\\\\x = 360[/tex]

The displacement of the skier during the second minute is calculated as follows;

[tex]x= (x_2 - x_1)\\\\x = 40 - 160\\\\x = -120 \ \\\\x = 120 \ west[/tex]

The displacement of the skier during the third minute is calculated as follows;

[tex]x = (x_3 - x_2)\\\\x = 120 - 40\\\\x = 80 \ east[/tex]

Answer:

Workdone is 5734.06Nm.

Explanation:

Given the following data;

Force applied = 125N

Angle = 35°

Distance = 56m

To find the workdone by the lawnmower, we would first of all find the horizontal component of the force applied.

[tex] Horizontal force, Fx = mgCosd[/tex]

Where;

mg = weight = 125N

Substituting into the equation, we have;

[tex] Fx = 125 * Cos35[/tex]

[tex] Fx = 125 * 0.8192[/tex]

Fx = 102.39N

Workdone is given by the formula;

[tex] Workdone = force * distance[/tex]

[tex] Workdone = 102.39 * 56[/tex]

Workdone = 5734.06Nm

Therefore, the work done by the lawnmower is 5734.06Nm.

Following are the solution to this question:

Explanation:

That light takes a very long time to hit the planet, and the object is far off the earth. The light of such an item near to the planet takes less time to enter it. The star is 2,5 million light-years from the Planet on the far side of the Andromeda Galaxy. But on the other hand, the moon is 15 crore miles from the earth, so sunlight is quickly reached on the ground as the other thing.  

That milky way away from the earth is 66,500 light-years far, that distance between Earth and Orion nebula is 1,344 light-years, with such a distance of 4,367 light-years. The earth is 5.2261 trillion km apart from Pluto.

Answer:

Explanation:

Given

Velocity = 388m/s

Height S = 2.89m

Required

Time

Using the equation of motion

S =ut+1/2gt²

2.89 = 388t+1/2(9.8)t²

2.89 = 388t+4.9t²

Rearrange

4.9t²+388t-2.89 =0

Factorize

t = -388±√388²-4(4.9)(2.89)/2(4.9)

t= -388±√(388²-56.644)/9.8

t = -388±387.93/9.8

t =0.073/9.8

t = 0.00744 seconds

What shouldJerome always keep constant for each object after the objects collide and bounce apart? That would be Mass.

Answer:

B: Mass

Explanation:

Answer:

The mass can be calculated by dividing the net force acting on an object by the acceleration of the object. When talking about net force, we use the units kilogram meter per second squared. This is also known as a Newton. The units for acceleration is meters per seconds squared, and the units for mass are kilograms.

Line D represents a stationary object.

When an object is stationary, the line on the graph is horizontal.

We know, that an object is stationary means the slope of its position-time graph is zero or its pt graph is a straight line parallel to the x-axis.

The nest, or the resting place, is a stationary object, and one cannot put one's foot in front of it. A string is then tied from the head assembly to another stationary object.

Answer:

a curved path generally goes around all hills and higherpoints in a trail, unlike a straight path which would take you through every single terrain there is on the mountain.

For a less steep slope, less power is needed by the vehicle. The concept is that it will be easier for one to exert less control and that too for a more extended period. So the roads of the mountains are always made curvy and not straight.

West =4.2m

Explanation:

Kindly see attached a rough draft of the situation

Step one

Given data

From the sketch the direction of the player is along the resultant of the triangle, corresponding to the Hypotenuse

Step two:

Hence for an opponent to tackle him towards the south, he must be at

sin θ= opp/hyp

sin 20=x/4.5

x=sin 20*4.5

x=0.342*4.5

x= 1.5m

Also, for an opponent to tackle him towards the south, he must be at

cos θ= adj/hyp

cos 20=y/4.5

y=cos 20*4.5

y=0.93*4.5

y= 4.2m

but if not then it would be A. Examining how much diet influences the effects of exercise.

It looks like the diagram is telling you that there is a net force of 8 N + 4 N = 12 N pointed to the right. By Newton's second law, the magnitude of the net force F is equal to the mass m times the acceleration a :

F = m a

12 N = (4 kg) a

a = (12 N) / (4 kg)

a = 3 m/s²
