(a) The free body of all the forces include, frictional force, weight of the box acting perpendicular and another acting parallel to the plane.

(b) When the box is sliding down, the frictional force acts towards the right.

(c) When the box slides up, the direction of the frictional force changes, it acts towards the left.

The free body diagram of all the forces on the box is obtained by noting the upward force and downward forces on the box as shown below;

                      /  W2

                    Ф → Ff

                    ↓W1

where;

(b) When the box is sliding down, the frictional force acts towards the right.

(c) When the box slides up, the direction of the frictional force changes, it acts towards the left.

Answer:

The answer is 2N

Explanation:

Now,

Radius (r) = Diameter ÷ 2

r = 1/2

r = 0.5 mm = 5 × 10‾⁴

T = 3.14 ÷ 10 = π/10 sec

∴ F = mrω² = mr (2π/T)² = 4π²mr/T²

F = 4 π² × 10 × 5 × 10‾⁴/(π/10)²

F = 4 π² × 10 × 5 × 10‾⁴ × 100/π²

F = 4 × 0.5

F = 2 N

Thus, The centripetal force acting on it is 2 Newton

Answer:

To keep from falling at the top;

M V^2 / R = M g

This can be rewritten

1/2 M V^2 = M g R /2

2 M g R = 1/2 M V^2     difference in KE between top and bottom

2 M g R + M g R / 2 = 5/2 M g R

Adding the minimum KE at the top to the KE gained when the potential energy of 2 M g R is converted to KE

Answer:

For how long must an object travel at 29.8km/s to cover 940Gm? t = 940 Gm 29.8 km/s = 940 ⋅ 1 0 9 m 29.8 ⋅ 1 0 3 m s = 9.4 ⋅ 1 0 11 m 2.98 ⋅ 1 0 4 m s ≈ 3.154 ⋅ 1 0 7 s .

Explanation:

It will take 3,15,43,674 sec to cover a distance of 940 Gm with a speed of 29.8 km/s.

Speed [s], distance [d] and time [t] are related to each other by the following relation -

s = d/t

Given is an object travelling at 29.8 km/s in order to cover 940 Gm.

In 1 Gm(Gigameter) there are 1000000000 m or 10⁹ m

Speed of object [s] = 29.8 km/s = 29800 m/s.

Distance to be covered [d] = 940 x 10⁹ m

Time taken to cover the distance of 1 Gm will be -

t = 1 Gm / 29800

t = (10⁷ x 100) / 29800

t = 10⁷/ 298

t = 33557.1 seconds

Therefore, in order to travel 940 Gm, it will take -

940 x 33557.1 = 3,15,43,674 sec

Therefore, it will take 3,15,43,674 sec to cover a distance of 940 Gm with a speed of 29.8 km/s.

Answer: Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related ( Step 1 ), you can make predictions that are specific and testable

Explanation:

A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.

The given magnitude of forces of F₁ = F₄, F₂ = F₃, F₁ = 2·F₂, give the

forces that exert zero net torque on the disk as the options;

(B) F₂

(D) F₄

The given parameters are;

F₁ = F₄

F₂ = F₃

F₁ = 2·F₂

Therefore;

F₄ = 2·F₂

In vector form, we have;

[tex]\vec{F_4} = \mathbf{\frac{\sqrt{3} }{2} \cdot F_4 \cdot \hat i - 0.5 \cdot F_4 \hat j}[/tex]

[tex]\vec{F_2} = \mathbf{ -F_2 \, \hat j}[/tex]

Clockwise moment due to F₄, M₁ = [tex]-0.5 \times F_4 \, \hat j \times \dfrac{R}{2}[/tex]

Therefore;

[tex]M_1 =- 0.5 \times 2 \times F_2 \, \hat j \times \dfrac{R}{2} = \mathbf{ -F_2 \, \hat j \times \dfrac{R}{2}}[/tex]
