Answer:

17.64 Newtons

Explanation:

In order to find the weight of an object we take the mass in kilograms and multiply it by the gravitational constant (9.8), which is 1.8 * 9.8 = 17.74 Newtons.

Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Weight of body is force due to gravity,

F = mg

F = 1.8*9.8

F = 17.64 N

Weight of the body is given as 17.64 N.

Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

Answer:

C. She is not releasing the endorphins that she used to, and that impacts her sleep.

Explanation:

The best explanation for why Therese is having trouble sleeping is that she is not releasing the endorphins that she used to, and that impacts her sleep.

Hence, the correct option is C.

Endorphins are hormones that are released during exercise. They have mood-boosting and pain-relieving effects. When Therese stops exercising, she is no longer releasing as many endorphins, which can lead to moodiness and difficulty sleeping.

Option A is incorrect because exercise does not directly move oxygen through the blood. Instead, it increases the heart rate and breathing rate, which in turn increases the amount of oxygen that is delivered to the tissues.

Option B is incorrect because there is no evidence to suggest that Therese requires more exercise than most people to relieve stress. In fact, most people find that regular exercise can help to reduce stress levels.

Option D is incorrect because it is unlikely that Therese is not maintaining the healthy habits that she did when she was practicing. Lacrosse is a physically demanding sport, so it is likely that Therese is still eating healthy and getting enough sleep.

Therefore, the best explanation for why Therese is having trouble sleeping is that she is not releasing the endorphins that she used to, and that impacts her sleep.

Hence, the correct option is C.

Answer:

because the knife is sharp

Answer:

Pressure is inversely proportional to the area of the surface. While a blunt knife has more area coming in contact than a sharp knife and the pressure exerted by the blunt knife will be less as compared to that of a sharp knife. Therefore it is easier to cut with a sharp knife.

Answer:

Efficiency: 0.4 (40%)

Explanation:

The efficiency of a simple machine is given by the ratio

n = w¹/w²

where

w² is the input work of the machine

w¹ is the output work of the machine

For the machine in this problem, we have:

w¹ = 800j is the output work

w² = 2000j is the input work

Therefore, the efficiency of the machine is

n = 800/2000 = 0.4

Which can be also written as percentage:

n = 0.4 × 100 = 40%

Answer:

I guess it is the reason

Explanation:

A dam is thicker at the bottom than at the top because the forces exerted are strongest close to the ground. Water pressure increases proportionally with depth, so the lower portion of the dam has greater water pressure exerted upon it. The increasing thickness of the lower dam also helps it support its own weight.

This is because of Pressure.

Pressure is directly proportional to depth and the deeper the length the high the pressure. Thus at the bottom, water pressure is very high and the walls must be made thicker to accommodate that pressure.

1.  Describe a situation in which the force required to change the velocity of an object changes based on the mass of the object.

Place both a volleyball and a bowling ball on the lower surface of an inclined plane (e.g., on an asphalt road going uphill).  Roll each one up the hill and measure the difference in effort (force) each requires to start moving.

2. Describe a simple experiment you could perform that would generate data to provide evidence that the change in an object’s motion depends on either the forces on the object or the mass of the object.

Use a coiled spring to propel two objects above (volleyball and bowling ball) and observe both the distance and the velocity after leavging the spring.

Answer:

A rotating fan completes 1200 revolutions every minute. Consider the tip of a blade, at a radius of 0.15 m.

Explanation:

The tangential velocity at the point, 0.16 m from the axis is 13.44 m/s.

We have the following information;

Angular speed of the blade = 800rev/min

Radius of the point under consideration = 0.16m

We have to convert the angular velocity to units of rad/s

Given that;

1 rev/min = 0.105 rad/s

800rev/min = 800rev/min × 0.105 rad/s/1 rev/min

= 84 rad/s

Now;

v = rω

v = Tangential velocity

r = radius

ω = angular velocity

v =  0.16m × 84 rad/s

v = 13.44 m/s

Explanation:

Every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.

Anything which has mass to keep the same when comparing the hardness of the solid and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.

As given in the problem statement we have to find the true statement from the given options that is true for every atom of an element,

The size of an atom of an element is a very small order of magnitude so it can not be seen with a magnifying glass, therefore, option A is not the correct response.

Thus, every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.

The equilibrium condition allows finding the result for the tension of the cable that supports the block is:

Newton's second law gives a relationship between force, mass and the acceleration of bodies, when the acceleration is zero it is called the equilibrium condition.

A free-body diagram of the forces is shown in the attachment.

Let's write the equilibrium equation for the vertical axis.

        2 [tex]T_1_y[/tex] - f - W = 0

          2 [tex]T_1_y[/tex]  = W + f

Let's use trigonometry to find the tension, as the angle indicates that it is relative to the vertical.

        cos 30 = [tex]\frac{T_1_y}{T_1}[/tex]  

        [tex]T_1_y[/tex]  = T1 cos 30

We substitute.

        2T₁ cos 30 = W + f

         T₁ = m g + f / 2 cos 30

         T₁ = [tex]\frac{6 \ 9.8 + 410}{2 \ cos 30}[/tex]  

         T₁ = 270.66 N

In conclusion using the equilibrium condition we can find the result for the tension of the cable that supports en bloc is:

Using the information depicted on the distance - time graph, the slope of the graph is could be used to infer the velocity of each cyclist. Hence, cyclist A and B do not have the same velocity at 3 seconds.

The steepness of slope on the distance - time graph gives the velocity of the cyclist. At time, t = 0 ; the cyclist A has a greater slope than cyclist B. Hence, the velocity of the cyclists is different.

Therefore, the cyclists do not have the same velocity at time, t = 3 seconds.

The final temperature of the water is 106.0 °C

From the question,

We are to determine the final temperature of water.

From the formula

Q =mcΔT

Where Q is the quantity of heat

m is the mass of substance

c is the specific heat capacity of substance

and ΔT is the change in temperature

Also,

ΔT = T₂ - T₁

Where T₂ is the final temperature

and T₁ is the initial temperature

Then, the formula can be written as

Q =mc(T₂ - T₁)

From the question

Q = 7500 J

m = 250 g

T₁ = 98.8 °C

Putting the parameters into the formula, we get

7500 = 250 × 4.184 (T₂ - 98.8)

(NOTE: specific heat capacity of water, c,= 4.184 J/g °C)

7500 = 1046 (T₂ - 98.8)

7500 = 1046T₂ - 103344.8

Then,

1046T₂ = 7500 + 103344.8

1046T₂ = 110844.8

∴ T₂ = 110844.8 ÷ 1046

T₂ = 105.9701 °C

T₂ ≅ 106.0 °C

Hence, the final temperature of the water is 106.0 °C.
