Answer:
State vector.
Explanation:
To determine exactly where a satellite is located, engineers must think and calculate positions in three dimensions. A set of data telling engineers all of the various elements of position, velocity, and time for a satellite or spacecraft is known as a state vector.
This ultimately implies that, state vectors gives a detailed description of the position and velocity of a satellite at a specific period of time. Also, the more accurate your input state vector, the more accurate would be the position, velocity and time for a satellite when trying to determine its location. Therefore, the time tag of a state vector shouldn't be too far from the present time of the day.

The image formed by the location of object is beyond 2F the image by convex lenses is between F and 2F and is inverted, smaller and and real image. If it is at 2F, the image is inverted with the same size and real.
What is a convex lens ?A convex lens is a type of lens that is projected outwards and shows the real image of an object. Whereas a concave lens is curved inwards and shows virtual image of objects.
The image formed at by the location of convex lenses beyond 2F is inverted, smaller and and real image. If it is at 2F, the image is inverted with the same size and real. If the lens is placed between F and 2F the image formed is beyond 2F and it will be inverted, enlarged and real.
If the object is at F , no image will be formed. If it at between F and the lens, then the image forms beyond 2 F which is upright, enlarged and virtual.
The object be at any position with respect to the focal length of lens, the image formed by a concave lens is between F and the lens and upright, small and virtual.

3V battery is used with a 15 ohm resistance.What is the current?
Answer:
0.2 A
Explanation:
V= IR
3 = I × 15
I = 3/15
= 1/5 = 0.2 A
The flow of current in a battery will be "0.2 A". To understand the calculation, check below.
Current, Resistance and VoltageAccording to the question,
Voltage, V = 3 V
Resistance, R = 15 ohm
We know the relation,
→ Voltage (V) = Current (I) × Resistance (R)
or,
→ Current, I = [tex]\frac{V}{R}[/tex]
By substituting the values,
= [tex]\frac{3}{15}[/tex]
= 0.2 A
Thus the above answer is correct.

high at a speed of 0.36 m/s. Her power output vertically is-
Answer:
180Watts
Explanation:
Power = Force * distance/Time
Given
Force = 500N
Distance = 18m
Time t = 50secs
Substitute into the formula
Power = 500*18/50
Power = 10 * 18
Power = 180Watts
Hence her power output vertically is is 180Watts
How do you prove you know which object has more momentum without calculating it?
Answer:
The momentum of an object varies directly with the speed of the object.
Explanation:
Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum. A less massive object can never have more momentum than a more massive object.

Two spherical shells have a common center. A -1.50 × 10-6 C charge is spread uniformly over the inner shell, which has a radius of 0.050 m. A +4.50 × 10-6 C charge is spread uniformly over the outer shell, which has a radius of 0.15 m.Find the magnitude and direction of the electric field at a distance (measured from the common center) of______________.
a: 0.20m
b: 0.10m
c: 0.025m
Answer:
a) At 0.20 m, the magnitude of the field is 675.0 kV
The direction of the field is acting outwards from the center of the charged spheres
b) At 0.10 m, the magnitude of the field is 135 kV
The direction is acting outwards from the center of the charged spheres
c) At 0.025 m
The magnitude of the field, V = -270.0 kV
The direction of the field is inwards, towards the center of the charged spheres
Explanation:
The charged spherical shell parameters are;
The charge on the inner sphere, q₁ = -1.50 × 10⁻⁶ C
The radius of the inner shell, R₁ = 0.050 m
The charge on the outer sphere, q₂ = +4.50 × 10⁻⁶ C
The radius of the outer shell, R₂ = 0.15 m
Let 'r', represent the distance at which the electric field is measured, the following relationships can be obtained;
When r < R₁ < R₂,
[tex]V = k \cdot \left( \dfrac{q_1}{R_1} + \dfrac{q_2}{R_2} \right )[/tex]
When R₁ < r < R₂,
[tex]V = k \cdot \left( \dfrac{q_1}{r} + \dfrac{q_2}{R_2} \right )[/tex]
When R₁ < R₂ < r,
[tex]V = k \cdot \left( \dfrac{q_1 + q_2}{r^2} \right )[/tex]
a) When r = 0.20 m, we have;
R₁ < R₂ < r, therefore
[tex]V = k \cdot \left( \dfrac{q_1 + q_2}{r^2} \right )[/tex]
By plugging in the values, we get;
[tex]V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6} + 4.50\times 10^{-6} }{0.20^2} \right ) = 675.0 \ kV[/tex]
Therefore, the magnitude of the field, V = 675.0 kV
The direction of the field is outwards
b) When r = 0.10 m, we have;
When R₁ < r < R₂, therefore;
[tex]V = k \cdot \left( \dfrac{q_1}{r} + \dfrac{q_2}{R_2} \right )[/tex]
By plugging in the values, we get;
[tex]V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6} }{0.10} + \dfrac{4.50\times 10^{-6}}{0.15} \right ) = 135 \ kV[/tex]
Therefore, the magnitude of the field, V = 135 kV
The direction of the field is outwards from the center
c) When r = 0.025 m, we have;
When r < R₁ < R₂, therefore;
[tex]V = k \cdot \left( \dfrac{q_1}{R_1} + \dfrac{q_2}{R_2} \right )[/tex]
By plugging in the values, we get;
[tex]V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6} }{0.05} + \dfrac{4.50\times 10^{-6}}{0.15} \right ) = -270 \ kV[/tex]
Therefore, the magnitude of the field, V = -270.0 kV
The direction of the field is inwards, towards the center of the charged spheres.
Typical Pressurized Water Reactors can produce 1100 to 1500
megawatts, or about _______
Joules/second.
Answer: about 1,100,000,000 to 1,500,000,000 Joules/second
Explanation:
1 MW (megawatt) = 1,000,000.00 J/s (joules per second)
1100(1,000,000) = 1,100,000,000
1500(1,000,000) = 1,500,000,000

What is law of conservation of linear momentum?According to the law of conservation of linear momentum, the sum of the momentum of the bodies which are collided with each other must be equal before and after the collision.
m₁ .u₁ + m₂.u₂ = m₁ .v₁ + m₂.v₂
where m₁ and m₂ is the masses, u₁ and u₂ are initial speed while v₁ & v₂ is their final speed of the collieded objects.
Linear momentum can be defined as the product of the mass times the velocity of that object.
Given, the initial velocity of the baseball is u₁ = 15 m/s
The initial velocity of the tennis ball u₂ = 22 m/s.
The mass of baseball, m₁ =0.15 Kg
From the law of conservation of momentum, find the mass of the tennis ball:
m₁ u₁ + m₂ u₂ = m₁.v₁ + m₂.v₂
0.15 × 15 + m ×22 = 0.15 × 1.2 + m × 13
2.25 + 22 m = 0.18 + 13 m
9 m = 2.25
m = 0.23 Kg

Answer:
the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
Explanation:
Given;
applied force, F = 5000 N
cross sectional area of the steel wire, A = 0.2 m²
The tensile stress of the steel wire, is calculated as;
[tex]\sigma = \frac{F}{A} \\\\\sigma = \frac{500}{0.2} \\\\\sigma = 2500 \ N/m^2\\\\\sigma = 2.5 \ \times \ 10^3 \ Nm^{-2}[/tex]
Therefore, the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
A solid wooden cube, 30cm on each side can be totally submerged in water if it is pushed downward with a force of 54N. What is the density of the wood?
Answer:
the density of the wooden cube is 204.1 kg/m³
Explanation:
Given;
applied force, F = 54 N
length of each side of the solid wooden cube, L = 30 cm = 0.3 m
mass of the wooden cube is calculated as;
F = mg
m = F/g
m = 54/9.8
m = 5.51 kg
The volume of the wooden cube is calculated as;
V = L³
V = (0.3)³
V = 0.027 m³
The density of the wooden cube is calculated as;
ρ = m/V
ρ = (5.51 kg) / (0.027 m³)
ρ = 204.1 kg/m³
Therefore, the density of the wooden cube is 204.1 kg/m³
