Answer:

3 m/s

Explanation:

The computation of speed is shown below:-

We will compute the equation by using the law of conservation of momentum; also, the total momentum prior and following the collision must be conserved. Therefore we can write the equation is the following manner:-

[tex]m_1 u_1 + m_2 u_2 = (m_1 +m_2)v[/tex]

where the symbols represent

150 kg is the mass of spaceship 1  = m1

150 kg is the mass of spaceship 2  = m2

0 m/s is the initial velocity of spaceship 1  = u1

6 m/s is the initial velocity of spaceship 2 = u2

and v is the velocity of the 2 ships so that they can collide and combined together

For v we will get the following equation to reach the speed

[tex]v=\frac{m_1 u_1 + m_2 u_2}{m_1+m_2}[/tex]

[tex]=\frac{0+(150)(6)}{150+150}[/tex]

[tex]=3 m/s[/tex]

Answer:

+2

Explanation:

Because electrons are negative so if electrons are lost then it will automatically become positive in this case +2. This will be right if there are then more electrons than protons in total. I pretty sure it's correct.  

Explanation:

It is given that,

Mechanical advantage of a ramp is 4

It is used to move a 38 N load

We need to find the force needed to push the load up the ramp. The mechanical advantage is equal to the ratio of output force to the input force. We have output force as 38 N

So,

[tex]4=\dfrac{38}{F_i}\\\\F_i=\frac{38}{4}\\\\F_i=9.5\ N[/tex]

So, the force of 9.5 N is needed to push the load up the ramp.  

Grains, pasta, etc provides the body with energy in the form of carbohydrates because they're absorbed quickly by the body and used for energy.

Answer:

k₁ = 2πf₁/v

k₂ = 2πf₂/v

Explanation:

Since the de Broglie relation λ=h/p (1 ) and momentum, p =kℏ (2)

From (1) p = h/λ = kℏ

So,  h/λ = kℏ

Hence, k = h/ℏλ  since ℏ = h/2π and wavelength, λ = v/f, substituting these two into k, we have

k = h/[(h/2π)(v/f)]

k = 2πf/v where k = wave number, f = frequency of wave and v = velocity of wave.

Now, for the first wave number k₁, k₁ = 2πf₁/v

for the second wave number k₂, k₂ = 2πf₂/v

Answer:

here is the answer

Explanation:

initial velocity= u= 0

final velocity = v

acceleration= 1.30m/s²

time= 6 seconds

using formula

a = v-u/t

1.30 = v - 0/6

1.30*6 = v - 0

7.8= v - 0

7.8 = v

therefore, final velocity is 7.8 m/s

[tex]F_{y}[/tex] = 700000 N(sen 90° - 20°) - 560000 N = 97785 N

The approximate vertical component of the net force that is propelling the rocket away from Earth is 112,000 N. Option B is correct.

The net force acting on the rocket is the sum of the thrust force and the weight of the rocket. The thrust force is pointing upwards at an angle of 20 degrees, and the weight of the rocket is pointing downwards. The thrust force is the force that is generated by the rocket engine. It is the force that propels the rocket upwards.

The weight of the rocket is the force of gravity acting on the rocket. It is the force that pulls the rocket downwards. The net force acting on the rocket is the sum of the thrust force and the weight of the rocket. If the net force is positive, the rocket will accelerate upwards. If the net force is negative, the rocket will accelerate downwards. If the net force is zero, the rocket will remain at rest.

net force = thrust force + weight

vertical component of net force = thrust force * cos(angle)

vertical component of net force = 700,000 N * cos(20 degrees) = 112,000 N. Option B is correct.

Answer:

1) 916 kg/m³

2) 9.8566×10⁴ Pa

Explanation:

1) Originally, the water is at the same level on both sides.  When the oil is added, one side goes down 67.5 mm and the other side goes up 67.5 mm.  The top of the oil is 12.3 mm above the water, so the total height of the oil relative to the low end of the water is:

12.3 mm + 67.5 mm + 67.5 mm = 147.3 mm

And the height of the water relative to the low end is:

67.5 mm + 67.5 mm = 135 mm

The pressure at the bottom of the oil equals the pressure of the water at the same elevation.

P = P

ρgh = ρgh

ρh = ρh

ρ (147.3 mm) = (1000 kg/m³) (135 mm)

ρ = 916 kg/m³

2) P = ρgh

P = (1.3608×10⁴ kg/m³) (9.7835 m/s²) (0.74035 m)

P = 9.8566×10⁴ Pa

Answer:

v = 6 cm

Explanation:

We have,

A small object is placed on the principal axis of a convex mirror of focal length 10 cm. The focal length of a convex mirror is positive. So, f = +10 cm

It is required to find the position of the image when the object is 15 cm from the mirror.​ Using mirror's formula :

[tex]\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}[/tex]

v is image distance

[tex]\dfrac{1}{v}=\dfrac{1}{f}-\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{+10}-\dfrac{1}{(-15)}\\\\v=6\ cm[/tex]

Hence, the image will formed at a distance of 6 cm form the mirror.

it is very hard but i am trying to help you.

Explanation:

Answer: Slope = - 1000.

Explanation:

The line of best fit of the graph will be linear.

The general linear equation can be expressed as;

Y = MX + C

Where the Y variable represents the volume in the experiment as dependent variable and the X represent the pressure as independent variable.

The equation can be rewritten as:

V = MP + C

Where C is the intercept.

Given that

V = 200, 100, 50, 25, 12.5 and

Pressure P = 0.1000, 0.2000, 0.4000, 0.8000, 1.6000

The slope M can be calculated by using the formula

M = (V2 - V1)/ (P2 - P1)

Where V1 = 200, V2 = 100, P1 = 0.1, P2 = 0.2

Substitute all the parameters into the formula

M =( 100 - 200)/ ( 0.2 - 0.1 )

M = -100/0.1

Slope M = - 1000

Radius = 3.5 m

The tangential speed is given as:

V = Radius × ω

ω = angular speed = (2 × pi) / T

ω = (2 × 22/7) / 8.2

ω = 6.2857142 / 8.2

ω = 0.7665505

Therefore, tangential speed (V) equals;

Let Charge of [tex]1\ \mu C[/tex] is taken from points A & B such that [tex]V_A-V_B=1000\ V[/tex].

We need to find the energy of charge. Electric potential is defined as the work done per unit of electric charge. So,

[tex]W=(V_B-V_A)q\\\\W=-1000\times 10^{-6}\\\\W=E=-10^{-3}\ J[/tex]

False, the process of converting a solid into liquid at its melting point is called melting.

What is fusion ?

When two light atoms combine to form a new heavier nucleus this process is known as fusion. For example, when two hydrogen atoms combine to form helium atom.

Upon reaching a substance's melting point, the heat supplied by the substance (latent heat of fusion) causes the molecules to drift apart and the substance changes state (solid to liquid) by increasing its internal energy, resulting in a temperature decrease and a change of state (solid to liquid).
