Your task now is to look up the effects of the temperature on an equilibrium and how the reaction will shift when adding or removing heat. Explain in no less than 4 complete sentences the effect of the temperature and list at least on example.

Answers

Answer 1

Answer:

If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. It will do that by favouring the reaction which absorbs heat. In the equilibrium we've just looked at, that will be the back reaction because the forward reaction is exothermic.

A baseball is thrown straight upward with a speed of 30 m/s. (a) How long will it rise? (6) How high will it
rise? (c) How long after it leaves the band will it return to the starting point? (ch) When will its speed be
16 m/s?

Answers

Answer:

(a) 3.06 s

(b) 45.92 m

(c) 6.12 s

(ch) 1.43 s

Explanation:

Vertical Launch Upwards

In a vertical launch upwards, an object is launched vertically up without taking into consideration any kind of friction with the air.

If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:

[tex]\displaystyle h_m=\frac{v_o^2}{2g}[/tex]

Similarly, the time it needs to reach the maximum height is:

[tex]\displaystyle t_m=\frac{v_o}{g}[/tex]

The object's speed (vf) after time t is:

[tex]v_f=v_o-g.t[/tex]

The baseball is thrown up at vo=30 m/s.

(a) It's required to calculate the time it needs to reach the maximum height:

[tex]\displaystyle t_m=\frac{30}{9.8}=3.06[/tex]

[tex]t_m=3.06~s[/tex]

(b) The maximum height is:

[tex]\displaystyle h_m=\frac{30^2}{2(9.8)}=45.92[/tex]

[tex]h_m=45.92~m[/tex]

(c) The time needed to travel up is the same time required to return to the starting point:

[tex]t_f=2*t_m=2*3.06[/tex]

[tex]t_f=6.12~s[/tex]

(ch) The speed will be vf=16 m/s at a certain time. Using the equation

[tex]v_f=v_o-g.t[/tex]

We solve for t:

[tex]\displaystyle t=\frac{v_f-v_o}{g}[/tex]

[tex]\displaystyle t=\frac{30-16}{9.8}[/tex]

t = 1.43 s

If Juan upgrades from a sports car to a large truck, what will happen to the
force needed to keep the truck going at the same speed? Use this
sentence frame:

Answers

Answer:

The force must increase

Explanation:

According to newton's second law "force is the product of mass and acceleration".

      Force  = mass  x acceleration

Now, the mass of the sports car is lesser compared to that of the truck. Therefore, to take both automobiles to the same speed, enough force must be applied by the engine of the truck.

There must be an increase in the force in order to make both automobiles attain the same speed.

Jill is pulling a 200. Newton sled through the snow at constant velocity using a horizontal force of 10. Newtons. What is the kinetic coefficient of friction of the sled on the snow?

Answers

Answer:

The kinetic coefficient of friction of the sled on the snow is 0.05

Explanation:

The given parameters are;

The weight of the sled Jill is pulling, W = 200 N

The force with which Jill is pulling the the sled = 10 Newtons

The nature of the speed with which the sled is pulled = Constant speed

Therefore, given that the only opposing force to the pulling of the sled = The force of kinetic friction, we have;

The force with which Jill is pulling the the sled = 10 Newtons = The force of kinetic friction, [tex]F_k[/tex]

The force of kinetic friction = The weight of the sled, W × The kinetic coefficient of friction of the sled on the snow, [tex]\mu _k[/tex]

[tex]F_k[/tex] = W × [tex]\mu _k[/tex]

[tex]\mu _k[/tex] = [tex]F_k[/tex]/W = 10 N/(200 N) = 0.05

The kinetic coefficient of friction of the sled on the snow = [tex]\mu _k[/tex] = 0.05.

The charge of a capacitor is 1500μC. Determine the potential difference between the plates if their capacitance is 5μF.

Answers

Answer:

The potential difference between the plates of the capacitor is 300V

Explanation:

Given;

capacitance of the capacitor, C = 5μF = 5 x 10⁻⁶ F

charge of the capacitor, Q = 1500μC = 1500 x 10⁻⁶ C

The potential difference between the plates of the capacitor is given by;

V = Q / C

Where;

V is the  potential difference between the plates

Q is the charge of the capacitor

C is the capacitance

[tex]V = \frac{Q}{C} \\\\V = \frac{1500*10^{-6}}{5*10^{-6}} \\\\V = 300 \ volts[/tex]

Therefore, the potential difference between the plates of the capacitor is 300V

Find the force of gravity between a cubic meter of water (1000kg) and the Sun. The Sun's mass is 1.99 x10^30 kg and is 1.50 x10^11 m away.
A) 17.0 N
B) 5.90 N
C) 2.0 N
D) 47.20 N

Answers

Answer:

F = 5.9 N

Explanation:

Given that,

Mass of water, m₁ = 1000 kg

Mass of the Sun, [tex]m_2=1.99\times 10^{30}\ kg[/tex]

Distance between two bodies, [tex]r=1.5\times 10^{11}\ m[/tex]

We need to find the force of gravity between water and the Sun. The formula for the gravitational force between two bodies is given by :

[tex]F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{1000\times 1.99\times 10^{30}}{(1.5\times 10^{11})^2}\\\\F=5.89\ N[/tex]

or

F = 5.9 N

The 2020 Ford police interceptor has a max acceleration of 4.4 m/s2. If a policeperson is sitting on
the roadside when a speeding car passes them at 70 mph (31.3 m/s), and the policeperson takes off
at max acceleration 1 second later, will they be able to catch the speeder in 10 seconds?
(Show work)

Answers

Answer:

The policeperson will not be able to catch the speeder in 10 seconds

Explanation:

The maximum acceleration of the 2020 Ford police interceptor, a = 4.4 m/s²

The rate at which the speeding car is moving, v = 70 mph (31.3 m/s)

The time after which the policeperson takes off = 1 second

The time, t, at which the policeperson catches the speeding car is given as follows;

s = u·t + 1/2·a·t²

Where;

u = The initial velocity of the Ford police interceptor = 0

∴ s = 0 × t + 1/2·a·t² = 1/2·a·t²

s = 1/2·a·t²

s = v × (t + 1)

Equating both equations, gives;

v × (t + 1) = 1/2·a·t²

Substituting the values, we get;

31.3 × (t + 1) = 1/2 × 4.4 × t²

31.3·t + 31.3 = 2.2·t²

2.2·t² - 31.3·t - 31.3 = 0

By the quadratic formula, we have;

t = (31.3 ± √((-31.3)² - 4×2.2×(-31.3))/(2 × 2.2)

t ≈ -0.938 seconds or t ≈ 15.165 seconds

The policeperson will catch the speeder in approximately 15.165 seconds

Therefore, the policeperson will not be able to catch the speeder in 10 seconds.

How much force is required to accelerate an 8 kg mass at 5 m/s2

Answers

Answer: 40 N

Explanation: Use the formula

F = m a

to solve this.

F = (8 kg) (5 m/s²)

F = 40 kgm/s²

F = 40 N

The required force will be "40 N".

The given value are:

Acceleration,

a = 8 kg

Mass,

m = 5 m/s²

The force will be:

→ [tex]Force (F) = Mass(m)\times Acceleration (a)[/tex]

By substituting the values, we get

                   [tex]= 5\times 8[/tex]

                   [tex]= 40 \ N[/tex]

Thus the response above is right.
