The Acceleration of the system is 6.41 m/s².

Given,

α= 15°, m₁ = 7kg

β= 65°, m₂ = 11 kg

Let, a be the acceleration and T is the tensions at the end it's the cord.

Let, the mass m₂ be coming down along the inclined plane along the inclined surface towards downward m₂g sin β and the tension in the upward direction,

Resultant force, m₂a=m₂g sin β -T

11a=((11) ×g sin 65°) -T  ...(i)

Now, considering the motion of m₁ which moves downwards, the forces are m₁g sinα, and T both are acting downwards.

Resultant force m₁a = m₁g sin α+T

7a =7g sin 15°+T  ...(ii)

Solving both the equations by adding them,

18a=11gsin 65°+7g sin 15°-T+T

18a=11gsin 65°+7g sin 15°=115.45

a=115.45/18=6.41 m/s²

Hence, the Acceleration of the system is 6.41 m/s².

The liquid A is present lower in the container as compared to liquid B due to more weight.

If two liquids A and B of relative densities 0.7 and 0.4 respectively then the lower density liquid remain at the top and higher density solution which is liquid A remains lower in the container because higher density solution has more weight.

So we can conclude that the liquid A is present lower in the container as compared to liquid B due to more weight.

Answer:Because if the shape gets changed it will move faster without to much weight

Explanation:

Answer:

E = K Q / R^2

E1 = K Q1 / R1^2 = K * (-6.39 E-9) / .4^2 = -K 39.9 E-9

E2 = K Q2 / R2^2 = K * 3.22 E-9 / .25^2 = K 51.5 E-9

Field will point to right of P since E2 (positive) stronger

E = K (E2 - E1) = 9.0 E9 * (51.5 - 39.9) E-9 = 104 N/C

The electric field at point P is 104.6 N/C.

Every place in space where a charge exists in any form has an electric attribute that can be defined as the electric field.

Here,

q₁ = -6.39 x 10⁻⁹C

q₂ = 3.22 x 10⁻⁹C

Distance from q₁ to P, d₁ = 0.4 m

Distance from q₂ to P, d₂ = 0.25 m

Electric field at P due to q₁, E₁ = k x -6.39 x 10⁻⁹/(0.4)²

E₁ = -39.9 x 10⁻⁹k N/C

Electric field at P due to q₂, E₂ = k x 3.22 x 10⁻⁹/(0.25)²

E₂ =51.52 x 10⁻⁹k N/C

Therefore, total electric field at P,

E = E₂ - E₁

E = (51.52 - 39.9) x 10⁻⁹k

E = 104.6 N/C

Hence,

The electric field at point P is 104.6 N/C.

when a bOdy rises into the air,the time it takes to reach a particular height is the same as the time it will take the body to fall from that height to the ground.

Answer:

Weaker, stronger

Explanation:

hope this helped!

Answer:

[tex]\fbox {weaker, stronger}[/tex]

Explanation:

The farther you bring charged objects from each other, the weaker the electrical force between them, and the bigger the charges on the objects, the stronger the electrical force between them.

Proving

Here we need the formula for Coulomb's Law, which is :

[tex]\boxed {F = \frac{1}{4\pi\epsilon_{0}}\times\frac{q_{1}q_{2}}{r^{2}}}[/tex]

As we can see, when the distance increases, the overall force will decrease as they are inversely proportional.

Similarly, as the product of charges is directly proportional to the electrical force produced, as the charges increase, the force increases.

Answer:

V = 26.95 cm³

Explanation:

Density is given by the formula :

ρ = m÷V

Density = mass ÷ Volume

Given both density and mass we rearrange, substitute and solve for Volume :

Rearranging the equation to make Volume the subject :

ρ = m÷V

ρV = m

V = m÷ ρ

Now substitute :

V = 45 ÷ 1.67

V = 26.9461077844

Take 2 decimal places as the density is 2 decimal places :

V = 26.95

Units will be cm³ as it is volume

Difference in air pressure helps us by contraction and relaxation of lungs  which forces air in and out of the lungs.

The pressure is the amount of force applied per unit area. It is represented as

Pressure p = Force/Area

The atmospheric pressure is constant. The flow of air is determined by how much above or below atmospheric pressure. The pressure inside the lungs rises or falls. The diaphragm in the lung contracts and relaxes  which forces air in and out of the lungs.
