Answer:

The acceleration of the spacecraft is 16,367.62 miles/hr²

Explanation:

Given;

thrust of the spacecraft, F = 5.31 x 10⁶ N

mass of the spacecraft, m = 5,760,000 lbm = 2612692.051 kg

The acceleration of the spacecraft in m/s² is given by Newton's second law of motion;

F = ma

a = F / m

a = \frac{5.31*10^6 \ N}{2612692.051 \ kg}\\\\a = 2.0324 \ m/s^2

The acceleration in miles per hour square is given by;

a =2.0324 \frac{m}{s^2} *\frac{0.0006214 \ mile}{m}*(\frac{3600 \ s}{1 \ hour})^2\\\\  a =2.0324 \frac{m}{s^2} *\frac{0.0006214 \ mile}{m}*\frac{12960000 \ s^2}{1 \ hour^2}\\\\a = 16,367.62 \ miles/hr^2

Therefore, the acceleration of the spacecraft is 16,367.62 miles/hr²

The elements selenium and oxygen are both poor electrical conductors. In which section of the periodic table are they
murzikaleks [220]

Answer:

The answer to your question is Nonmetals

Explanation:

Nonmetals   they are bad conductors of heat and electricity except graphite.

Metalloids   they are less conductors of electricity than metals.

Noble gases  they conduct electricity.

Halogens they are not metals and do not conduct electricity.

From this information, we conclude that Oxygen and Selenium are nonmetals.

a. 2.00kg object is subject to three force that gives acceleration a =8m/s^2 i +6m/s j if two of three forces are f1 =(30.0N)+(1
tekilochka [14]

By Newton's second law, the net force on the object is

∑ <em>F</em> = <em>m</em> <em>a</em>

∑ <em>F</em> = (2.00 kg) (8 <em>i</em> + 6 <em>j</em> ) m/s^2 = (16.0 <em>i</em> + 12.0 <em>j</em> ) N

Let <em>f</em> be the unknown force. Then

∑ <em>F</em> = (30.0 <em>i</em> + 16 <em>j</em> ) N + (-12.0 <em>i</em> + 8.0 <em>j</em> ) N + <em>f</em>

=>   <em>f</em> = (-2.0 <em>i</em> - 12.0 <em>j</em> ) N

An applied force<span> is a </span>force<span> that is </span>applied<span> to an object by a person or another object.
An attractive force is a force of an attraction (where object are attracted by each other). Gravitation is an example of attractive force.
</span>Normal force<span> is the component, perpendicular to the surface (surface being a plane) of contact.
</span><span>The softball experiences an applied force as a result of Amy’s throw. As the ball moves, it experiences attractive force from the air it passes through. It also experiences a downward pull because of the normal force.

In the first case:

when we heat any gas, the Kinetic Energy of the molecules increases, making it collide more frequently with the surface, increasing the pressure

more collisions with the surface means more force applied on it, which would push the piston harder than before, moving it outwards.

In the second case:

since the molecules inside the beaker have no way to escape, they would keep compressing the more you push the beaker downwards.

since there is the same number of molecules and lesser volume to cover, the molecules will start colliding with the surfaces more frequently, which would resist the downward force.

<em>another way to think about it is to imagine yourself where the trapped air is. you would be happy when the room is spacious but if the wall starts moving towards you, you would resist the change by your body because you need space to exist. making it harder for the wall to move.</em>

<em>pushing the beaker downwards will keep getting harder and harder the more you push until you reach a point where the molecules will be completely compact. applying even more force forces the molecules to enter water, removing the air that was resisting it all and making you able to get the beaker in water.</em>

Third case:

just like in the first case, the heated air will apply force on the surface, including the cork. which would pop off when enough force is applied.
