What is the gravitational force of attraction between two asteroids in space, each with a mass of 50,000 kg, separated
by a distance of 3800 m?
Answer:
1.16 x 10⁻⁸N
Explanation:
Given parameters:
Mass of the two asteroids = 50000kg
Distance between the asteroids = 3800m
Unknown:
Gravitational force between the two asteroids = ?
Solution:
To solve this problem, we apply the newton's law of universal gravitation:
Fg = [tex]\frac{G mass 1 x mass 2}{r^{2} }[/tex]
G is the universal gravitation constant
r is the distance between them
So;
Fg = [tex]\frac{6.67 x 10^{-11} x 50000 x 50000}{3800^{2} }[/tex] = 1.16 x 10⁻⁸N

I’m NC the wind is blowing from the north. If the wind changes direction and begins to blow from the south, what will most likely result.
NC means North Carolina.
Answer:
The temperatures will increase.
Explanation:
What will happen is that the temperature will increase. This is because, in wind direction and weather forecasting, a wind that shifts from the south means that warmer air/temperatures are approaching whereas a wind shift from the north implies that cooler air/temperatures are approaching.
A negative charge of -0.00067 C and a positive charge of 0.00096 C are separated by 0.7 m. What is the force between the two charges?
Answer:
-11,813.87N
Explanation:
According to coulombs law, the Force between the two charges is expressed as;
F = kq1q2/d²
k is the coulombs constant = 9*10⁹kg⋅m³⋅s⁻²⋅C⁻².
q1 = -0.00067 C
q2 = 0.00096 C
d = 0.7m
Substitute into the formula:
F = 9*10^9 * -0.00067 * 0.00096/0.7²
F = 9*10⁹*-6.7*10⁻⁴*9.6*10⁻⁴/0.49
F = -578.88*10⁹⁻⁸/0.49
F = -578.88*10/0.49
F = -5788.8/0.49
F = -11,813.87N
Hence the force between the two charges is -11,813.87N

27. A 20 kg object is at rest. A 6 N force pulls to the right on
the object for 10 seconds.
A) Find the impulse on the object.
B) Find the final momentum of the object.
C) What is its final velocity?
Answer:
a. 60 N*s
b. 60 (kg*m)/s
c. 3 m/s
Explanation:
Givens:
m = 20 kg
v_i = 0 m/s
t = 10 s
F = 6 N
a) Impulse:
I = F*t
I = 6 N*10 s
I = 60 N*s
b) Momentum:
p = v*m
F = m(a)
a = F/m
a = 6 N/20 kg
a = 0.3m/s^2
a = (v_f -v_i)/t
v_f = (0.3 m/s^2)*10 s
v_f = 3.0 m/s
p = 3 m/s*20 kg
p = 60 (kg*m)/s
c. Final velocity
a = (v_f -v_i)/t
v_f = (0.3 m/s^2)*10 s
v_f = 3.0 m/s
The impulse, momentum and final velocity can all be obtained from Newton's second law.
Let us recall that the impulse is obtained as the product of force and time.
Impulse = Force × time
Impulse = 6 N × 10 s = 60 Ns
From Newton's second law of motion;
F.t = mv - mu
Since the object was initially at rest;
F.t = mv
Hence, the final velocity of the object is 60 Kgms-1
The final velocity is obtained from;
F.t = mv
v = F.t/m
v = 6 × 10/20
v = 3 m/s

Answer:
[tex]1650\:\mathrm{m}[/tex]
Explanation:
We can use the following kinematics equations to solve this problem:
[tex]v_f=v_i+at,\\{v_f}^2={v_i}^2+2a\Delta x[/tex].

a person walks 60.0m and then walks 130m. what is the persons displacemnet if they walk east then west
Answer:
190
Explanation:
add because your looking for the Miles
When a person walks 60.0m and then walks 130m then the displacement of the person would be 70 meters if he first walked east and then west.
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.
As given in the problem a person walks 60.0m and then walks 130m and if he first walks east then west then we have to find the displacement.
Displacement = final position -initial position
Lets us consider eastward as positive direction,
displacement = 60 - 130
= -70 meters
The negative sign represents the displacement would be in a westward direction.
Thus, If a guy initially went east and then west, his displacement would be 70 meters when he traveled 60.0 meters and then 130 meters.

temperature of the mixture? The specific heat capacity of liquid water is
4180 J/kg.°C *
Will give brainliest and lot of stars please help
Answer:
T_finalmix = 45 [°C].
Explanation:
In order to solve this problem, a thermal balance must be performed, where the heat is transferred from water with the highest temperature, to the water with the lowest temperature, so the final temperature of the mix must be equal once the thermal balance is achieved.
[tex]Q_{water}=Q_{methanol}[/tex]
where:
[tex]Q_{water}=m_{water}*Cp_{water}*(T_{waterinitial}-T_{final})[/tex]
mwater = mass of the water = 300 [g] = 0.3 [kg]
Cp_water = specific heat of the water = 4180 [J/kg*°C]
T_waterinitial = initial temperature of the water = 80 [°C]
T_finalmix = final temperature of the mix [°C]
[tex]Q_{water}=m_{water}*Cp_{water}*(T_{final}-T_{water})[/tex]
Now replacing:
[tex]0.3*4180*(80-T_{final})=0.3*4180*(T_{final}-10)\\100320-1254*T_{final}=1254*T_{final}-12540\\112860=2508*T_{final}\\T_{final}=45[C][/tex]
The final temperature of the mixture is 45 °C
Data obtained from the question Mass of warm water (Mᵥᵥ) = 300 g = 300 / 1000 = 0.3 KgInitial Temperature of warm water (Tᵥᵥ) = 80 °C Mass of cold water (M꜀) = 300 g = 300 / 1000 = 0.3 KgInitial Temperature of cold water (T꜀) = 10 °C Specific heat capacity of water (C) = 4180 J/KgºC Equilibrium temperature (Tₑ) =? How to determine the equilibrium temperatureHeat lost by warm water = Heat gained by cold water
Qᵥᵥ = Q꜀
MᵥᵥC(Tᵥᵥ – Tₑ) = M꜀C(Tₑ – T꜀)
0.3 × 4180 × (80 – Tₑ) = 0.3 × 4180 × (Tₑ – 10)
1254 (80 – Tₑ) = 1254(Tₑ – 10)
Clear bracket
100320 – 1254Tₑ = 1254Tₑ – 12540
Collect like terms
100320 + 12540 = 1254Tₑ + 1254Tₑ
112860 = 2508Tₑ
Divide both side by 2508
Tₑ = 112860 / 2508
Tₑ = 45 °C
