Answer:

Tin fork and knife.....Copper coin...steel pole

Explanation:

Malleable objects are those which could be shaped with out breaking or could be turned into wires. Tin fork and knife could be bent so it is malleable, copper could be turned into wires so it is also malleable. Most of the metals are malleable. Mild Steel is used in making poles and pipes which is malleable

Answer:

In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).

Answer:

The height to which the ball flies is 86.6 m.

Explanation:

Given that,

Time = 2.05 sec

Acceleration = 9.8 m/s²

We need to calculate the initial velocity of volleyball

Using equation of motion

[tex]v=u-at[/tex]

Where, u = initial velocity

a = acceleration

t = time

Put the value into the formula

[tex]0=u-9.8\times(2.05)^2[/tex]

[tex]u=41.2\ m/s[/tex]

We need to calculate the height of the the ball

Using equation of motion

[tex]v^2=u^2-2ah[/tex]

Put the value into the formula

[tex]0=(41.2)^2-2\times9.8\times h[/tex]

[tex]h=\dfrac{(41.2)^2}{2\times9.8}[/tex]

[tex]h=86.6\ m[/tex]

Hence, The height to which the ball flies is 86.6 m.

D Distance and Mass

Answer:

C

Explanation:

Answer: malleability

Explanation:

¡Hellow!

For this problem, lets recabe information:

v (Velocity) = 10 m/s

a (Aceleration) = 1 m/s²

t (Time) = 1/4 min = 25 s

d (Distance) = ?

v' (Final velocity) = ?

First, for calculate distance, lets applicate formula:

                                        [tex]\boxed{\boxed{\text{d = Vo * t + (a * t}^{2})\text{ * 0,5} } }[/tex]

Lets replace according we information and let's resolve it:

d = 10 m/s * 25 s + (1 m/s² * (25 s)²) * 0,5

d = 250 m + (625 m) * 0,5

d = 2,5 m + 312,5 m

d = 314 meters.

Now, for calculate final speed, lets applicate formula:

                                                 [tex]\boxed{\boxed{\text{v' = v + a * t} } }[/tex]

Lets replace according we information and let's resolve it:

v' = 10 m/s + 1 m/s² * 25 s

v' = 10 m/s + 25 m/s

v' = 35 m/s

¿Good Luck?

Att: That guy who use the "ñ".

The answer would be newtons.

Responder:

Explicación:

Fuerza = Masa × aceleración

Dado que aceleración = velocidad final - velocidad inicial / tiempo

Fuerza = m (v-u) / t

Dado

Masa = 1000 kg

v = 15 m / s

u = 0 m / s

t = 20 segundos

Sustituye los valores dados en la fórmula para calcular la fuerza.

F = 1000 (15-0) / 20

F = 1000 (15) / 20

F = 15000/20

F = 750N

Answer:

Please show the warning's

Explanation:

The warning refers to the chemical property of the material or object that is flammable.

A chemical property is a feature that pertains to how a component, such as an ingredient or a compound, can alter as a result of a reaction. Due to bonding and other atomic structural characteristics, a substance develops these qualities as a result of its chemical identity.

Tactile or visual changes may occur in conjunction with chemical qualities. Chemical reactions commonly involve popping, fizzing, or the release of brilliant light. The emission of heat may also be a sign of a chemical reaction or chemical conversion that is taking place. Because the connections in the atomic structure are changing or breaking, these sensory clues appear.

Therefore, the warning refers to a chemical property of the material is flammable or combustible.

Answer: #3 and #5

Explanation:

Speed can be represented by many different units of distance and time.

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Speed is defined as distance per unit time so it's unit are meter per sec, kilo-meter per hour, that is different unit of distance and time.

Speed can be represented by many different units of distance and time.

Explanation:

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.

Nonmetals can form compounds through a process called covalent bonding.

Covalent bonding occurs when two nonmetal atoms share electrons to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outermost energy levels or achieve a noble gas electron configuration.

When two nonmetal atoms come together to form a compound, their electronegativities play a crucial role. Electronegativity is the ability of an atom to attract electrons toward itself in a chemical bond. If the electronegativities of the two nonmetals are similar, they will have a similar tendency to attract electrons, resulting in a more equal sharing of electrons.

So, nonmetals can form compounds through covalent bonding by sharing electrons. The extent of electron sharing depends on the electronegativity difference between the nonmetals involved, leading to either polar covalent or ionic bonding.

Therefore, nonmetals can form compounds through a process called covalent bonding.

Note: I'm assuming the data 77.3 is the mass of the crate.

Answer:

[tex]\mu_s =0.36[/tex]

Explanation:

The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).

[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]

The normal force is numerical equivalent to the weight of the body if no other external forces are acting.

[tex]N=m\cdot g[/tex]

The mass of the crate is m=77.3 Kg, thus its weight and normal force is:

[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]

[tex]N= 757.54\ Nw[/tex]

Now we calculate the coefficient:

[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]

[tex]\boxed{\mu_s =0.36}[/tex]

Answer:

0.36

Explanation:

Answer:

The graph that correctly shows the vertical velocity is B. since the velocity is negative and increases linearly over time

Explanation:

When an object is dropped from rest its movement is ruled only by the effect of gravity.

The acceleration of gravity [tex]g=9.8\ m/s^2[/tex] makes the object gain speed with a linear relation as shown:

vf = g.t

If we take the positive direction to be upward, then the speed will always be negative since the object will go against the positive direction.

Thus, the graph that correctly shows the vertical velocity is B. since the velocity is negative and increases linearly over time

From the given graphs, only the second graph (option B) started from rest (0) and later increased with time.

The given parameters;

The final vertical velocity of the rock X after a short time "t" is calculated as follows;

[tex]v_y_f = v_y_i + gt\\\\v_y_f = 0 + 9.8t[/tex]

The vertical velocity of the rock x will increase with time as it moves downwards.

Therefore, we can conclude that, from the given graphs, only the second graph (option B) started from rest (0) and later increased with time.
