Answer:

  0.6 seconds

Explanation:

The time to fall from height h is ...

  t = √(2h/g)

  t = √(2(1.86 m)/(9.8 m/s^2)) ≈ √0.3796 s ≈ 0.616 s

It would take about 0.6 seconds for the projectile to hit the ground.

Answer:

The weight of an object with mass M, in a place with gravitational acceleration G, is:

W = M*G

We know that in the moon, with G = 1.6 m/s^2, the weight is 160N

Then we have the equation:

160N = (1.6 m/s^2)*M

With this, we can find the mass of the astronaut.

(160N)/(1.6 m/s^2) = M = 100kg.

Then in the Earth, where the acceleration is G = 10 m/s^2, the weight will be:

W = (10m/s^2)*100kg = 1000 N

Answer:

The distance is now 4d

Explanation:

Mechanical Force

According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:

F = m.a

Where a is the acceleration of the object.

The acceleration can be calculated by solving for a:

[tex]\displaystyle a=\frac{F}{m}[/tex]

Once we know the acceleration, we can calculate the distance traveled by the block as follows:

[tex]\displaystyle d = vo.t+\frac{at^2}{2}[/tex]

If the block starts from rest, vo=0:

[tex]\displaystyle d = \frac{at^2}{2}[/tex]

Substituting the value of the acceleration:

[tex]\displaystyle d = \frac{\frac{F}{m}t^2}{2}[/tex]

Simplifying:

[tex]\displaystyle d = \frac{Ft^2}{2m}[/tex]

When a force F'=4F is applied and assuming the mass is the same, the new acceleration is:

[tex]\displaystyle a'=\frac{4F}{m}[/tex]

And the distance is now:

[tex]\displaystyle d' = \frac{4Ft^2}{2m}[/tex]

Dividing d'/d:

[tex]\displaystyle \frac{d' }{d}=\frac{\frac{4Ft^2}{2m}}{\frac{Ft^2}{2m}}[/tex]

Simplifying:

[tex]\displaystyle \frac{d' }{d}=4[/tex]

Thus:

d' = 4d

The distance is now 4d

Answer:

338.7cm

Explanation:

The can of corn would be in the shape of a cylinder. Since we are looking at capacity, we will want to find the volume.

V=abase×h

V=πr2×h

V=π(d2)2×h

V=π(6.62)2×9.9

V=338.7cm3

Hopefully this helps!

Answer:

338.7 cm³

Explanation:

For this question you use the volume formula of a cylinder πr²h.

Radius is 1/2 the diameter.

Simply input the variables into the formula.

π(3.3)²×9.9 = 107.811π or approximately 338.7 cm³

Cosmic Dust.

Why? When stars explode, or die, they releases dust and gas.

To solve this we must be knowing each and every concept related to galaxy. Therefore, cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Galaxies are collections of stars as well as other celestial objects that are gravitationally bound. The cosmos contains and over 100 billion galaxies, each of which has stunning formations seen in photographs captured by telescopes of the far sky.

According to Samuel, a galaxy's shape is the result of continual interactions between its many components. The majority of the mass is provided by the dark matter, which uses gravity to hold everything together. Cosmic dust of a galaxy consists of tiny particles that look smoky or cloudy and can be found in the space between stars.

Answer:

D. Time t = 1 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f}=v_{o}-g*t[/tex]

where:

Vf = final velocity = 0 (when the ball reaches the maximum height its elevation won't be increased since the velocity is zero)

vi = initial velocity = 10 [m/s]

g = gravity acceleration = 10 [m/s²]

t = time [s]

Now replacing:

[tex]0 = 10-10*t\\10 = 10*t\\t = 1 [s][/tex]

Answer: 5.8 m/s squared

Explanation: just got that question lol

Answer:

t=v/a

Explanation:

Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;

  Acceleration  = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]  

The change in velocity per unit of time is the acceleration

 From this equation;

      time  = [tex]\frac{change in velocity }{acceleration}[/tex]  

This expression is analogous to the expression chosen.

Answer:

Mercury shows faster increase in temperature than water on heating because the mercury has less specific heat capacity than water.

The specific heat capacity is defined as the amount of heat to required by a mass of a material to make a unit change in its temperature.  Mercury has less specific heat capacity and shows immediate changes in the temperature. Because of this mercury is used in thermometers and not water.

Mole = mass ÷ molar mass

Where;

Mole = mol

Mass = grams

Molar mass = g/mol

According to the information given in this question, number of moles = 3.1mol, mass of Hg = ?, Molar mass (MM) of Hg = 200.59g/lol

Hence, using mole = mass/MM

The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation:

P = ρgh

P = (1000 kg/m³)(9.8 m/s²)(4 m)

Answer:

P = ρgh  

P = (1000 kg/m³)(9.8 m/s²)(4 m)

P = 39200 Pa

Explanation:

In the case of the water stored in a tank, the pressure at its bottom is the weight acting on a unit area of the surface where the tank is kept. To turn that into an equation: Pressure = weight/area, and weight = mass (m) * acceleration due to gravity (g). This means pressure = m * g/ area

[tex]\boxed {\boxed {\sf 299.568 \ Joules }}[/tex]

Explanation:

Kinetic energy can be found using the following formula:

[tex]E_k=\frac{1}{2}mv^2[/tex]

where m is the mass and v is the velocity.

The mass of the person is 60 kilograms and the velocity is 3.16 meters per second

[tex]m= 60 \ kg \\v= 3.16 \ m/s[/tex]

Substitute the values into the formula.

[tex]E_k=\frac{1}{2} (60 \ kg) *(3.16 \ m/s)^2[/tex]

First, evaluate the exponent.

[tex]E_k=\frac{1}{2}(60 \ kg ) (9.9856 \ m^2/s^2)[/tex]

Multiply 60 kg by 9.9856 m²/s²

[tex]E_k=\frac{1}{2} (599.136 \ kg*m^2/s^2)[/tex]

Multiply 599.136 kg*m²/s² by 1/2, or divide by 2.

[tex]E_k=299.568 \ kg*m^2/s^2[/tex]

[tex]E_k= 299.568 \ J[/tex]

The running person has a kinetic energy of 299.568 Joules.

Solution:

We know that, Kinetic energy(kE)= 1/2×m×v^2

By applying formula,we get

Or,KE=1/2×60×3.16^2

Or,kE=299.57j

So,her kinetic energy is 2999.5j

Chemical reactions involves the chemical combination of two or more substances called REACTANTS to yield other substances called PRODUCTS. However, in accordance with the LAW OF CONSERVATION OF MASS, the amount of reactants must be equal to that of the products.

To accomplish this, the reaction must be BALANCED. A balanced equation is an equation in which the number of atoms of each element in the reactant side equals the number of atoms in the product side. In this reaction involving Aluminum and Oxygen to give Aluminum oxide as follows:

Al + 02 → Al2O3
