a. fast growth of hands and feet
b. increase in hip width
c. widening of the shoulders
d. lengthening of the torso

Answer:

yes, because you guy's are moving in a car. because if you think about it, your parents are driving, but the cars moving so basically you guys would be moving.

please mark as brainly

No your brother would appear to be stagnant ( i.e. Not moving )

Given that your brother is driving next to you at the same speed he would appear to be stagnant ( not moving ) to you.

When the basic factors of motion which are ;

Are the same the objects operating at the same factor values would appear not to be moving to each other.

Therefore we can conclude that your brother would appear to be stagnant to you ( i.e. Not moving )

Answer:

the cost of operating the light bulb is 72 cents.

Explanation:

Given;

cost of electricity, C = 6 cents / kW.h

power of light bulb, P = 100 W

time of light power consumption, t = 4 hours per day for 30 days

total time = 4 hours x 30 = 120 hours

Power consumed by the light bulb is calculated as;

P = 100 x 120 = 12000 w.h = 12 kW.h

Cost of power consumption = 6 cents/kWh x 12 kWh

                                               = 72 cents

Therefore, the cost of operating the light bulb is 72 cents.

Answer:

A.True

A ship is able to float on water because It is less dense than the water.

Explanation:

The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.

Answer:

Answer:

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.

Explanation:

Some sort of a local field, maybe not our A field, is really the cause of inertia. When you push on an object a gravitational disturbance goes propagating off into either the past or the future. Out there in the past or future the disturbance makes the distant matter in the universe wiggle.

Answer:

ACDE

Explanation:

Energy is generally described as the ability to do work by a body. There are two main forms of energy which are the kinetic energy and the potential energy.

Other energy forms stems from these two energy types.

             Potential energy  = mass x acceleration due to gravity x height

These description satisfies options A, C

             Kinetic energy  = [tex]\frac{1}{2}[/tex] x mass x velocity²

The description satisfies DE

Explanation:

The probes collect data, they capture the movement in space, therefore, spacecraft that carry instruments to collect data about objects in space are called probes, So the given statement is correct.

Any conductor that is placed into a plasma and gathers current is a probe. Measurements of the current on the probe as a function of the bias potential given to the probe can be used to identify a plasma's properties.

Such probes affect their surroundings while directly detecting electron and ion flows in the plasma. Any conductive material (wire, foil, chamber walls, etc.) can serve as a plasma probe; nevertheless, precise control over the probe's size, shape, and substance is necessary to achieve detectable plasma levels. Astronauts are not present aboard probes. Scientists can analyze the data the probes relay back to Earth. Sputnik 1 was the first spacecraft to launch.

Because probes probably collect data, they capture the movement in space, therefore, spacecraft that carry instruments to collect data about objects in space are called probes.

Answer:

h = 3.3 m (Look at the explanation below, please)

Explanation:

This question has to do with kinetic and potential energy. At the beginning (time of launch), there is no potential energy- we assume it starts from the ground. There, is, however, kinetic energy

Kinetic energy = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

Plug in the numbers = [tex]\frac{1}{2}[/tex](4.0)([tex]8^{2}[/tex])

Solve = 2(64) = 128 J

Now, since we know that the mechanical energy of a system always remains constant in the absence of outside forces (there is no outside force here), we can deduce that the kinetic energy at the bottom is equal to the potential energy at the top. Look at the diagram I have attached.

Potential energy = mgh = (4.0)(9.8)(h) = 39.2(h)

Kinetic energy = Potential Energy

128 J = 39.2h

h = 3.26 m

h= 3.3 m (because of significant figures)

Answer:

d = 1.65 m

Explanation:

Given that,

The speed of a ball, v = 3 m/s

A ball rolls a level table that is 1.5 m above the floor.

We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :

[tex]s=ut+\dfrac{1}{2}gt^2[/tex]

u is the initial speed in the vertical direction

So,

[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]

Now, using the formula of velocity.

[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]

So, the landing spot is at 1.65 m from the table.

Ultrasound and X-rays

Explanation:

A routine visit to a dentist consists of two areas of activities, including;

a) Dental examination and check up

b) Oral prophylaxis, and dental cleaning

The dental examination may involve the use of X-rays, which allow the detection of cavities between the teeth

The dental cleaning can be carried out with the use of an ultrasound cleaner, which allow the cleaning of sensitive teeth without hurting the patient

Therefore, the items most likely to be used during a routine dental visit are ultrasound and X-rays

sheet of metal required = 120.95 cm^2

Explanation:

Answer:

Given :-

A closed cylindrical tank of radius 3.5 m and height 2 m is made from a sheet of metal.

To Find :-

How much sheet of metal is required.

Formula Used :-

[tex]{\red{\boxed{\large{\bold{T.S.A\: of\: cylinder\: =\: 2{\pi}r(r + h)}}}}}[/tex]

where,

r = Radius

h = Height

Solution :-

Given :

Radius = 3.5 m

Height = 2 m

According to the question by using the formula we get,

⇒ [tex]\sf T.S.A =\: 2 \times \dfrac{22}{7} \times 3.5(3.5 + 2)[/tex]

⇒ [tex]\sf T.S.A =\: 2 \times \dfrac{22}{7} \times 3.5(5.5)[/tex]

⇒ [tex]\sf T.S.A =\: 2 \times \dfrac{22}{7} \times 3.5 \times 5.5T.S.A=2×722×3.5×5.5

⇒ \sf T.S.A =\: 2 \times \dfrac{22}{7} \times 19.25[/tex]

⇒ [tex]\sf T.S.A =\: 2 \times 60.5[/tex]

➠ [tex]\sf\bold{\purple{T.S.A =\: 121\: {m}^{2}}}[/tex]

∴ 121 m² of sheet of metal is required.

Answer:

[tex]K_1=4K_2[/tex]

Explanation:

Kinetic energy is given by

[tex]K=\dfrac{1}{2}mv^2[/tex]

m =  Mass of object

v = Velocity of object

Here mass is constant so

[tex]K\propto v^2[/tex]

[tex]v_1[/tex] = Intial velocity of the car = 20 m/s

[tex]v_2[/tex] = Final velocity of the car = 10 m/s

[tex]\\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow \dfrac{K_1}{K_2}=\dfrac{20^2}{10^2}\\\Rightarrow \dfrac{K_1}{K_2}=4\\\Rightarrow K_1=4K_2[/tex]

So, a car moving at 20 m/s has four times the translational kinetic energy of the same car moving at 10 m/s.

Generally speaking, scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.

Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. A small version of the Geologic Column is pictured at the right.
