Answer:

1.6675×10^-16N

Explanation:

The force of gravity that the space shuttle experiences is expressed as;

g = GM/r²

G is the gravitational constant

M is the mass = 1.0 x 10^5 kg

r is the altitude = 200km = 200,000m

Substitute into the formula

g = 6.67×10^-11 × 1.0×10^5/(2×10^5)²

g = 6.67×10^-6/4×10^10

g = 1.6675×10^{-6-10}

g = 1.6675×10^-16N

Hence the force of gravity experienced by the shuttle is 1.6675×10^-16N

Answer:

6m/s^2

Explanation:

Acceleration is the change in speed/Velocity per unit time. That means the speed divided by the time. 24m/s divided by 4s=6m/s^2

Furthermore, some modern watches (like smart watches) even incorporate calculators, GPS and Bluetooth technology or have heart-rate monitoring capabilities, and some of them use radio clock technology to regularly correct the time. Most watches that are used mainly for timekeeping have quartz movements.

Explanation:

To move maximum height the friction force can be assumed to be

negligible.

Reasons:

The component of the weight acting on the incline, w = m·g·sin(θ)

Length of the ramp = 15 m

Potential energy of the box = 15 × sin(θ) ×20 = 300·sin(θ)

F × 15 = 300·sin(θ)

F = 20·sin(θ)

Work done by net force = Potential energy gained by the box

Work done by net force = (40 - 20·sin(θ)) × 15 = 300·sin(θ)

40 = 20·sin(θ) + 20·sin(θ) = 40·sin(θ)

sin(θ) = 1

θ = arcsin(1) = 90°

The ramp is at an inclination of 90°, therefore, the ramp is oriented vertically

The height of the ramp = The length of the ramp = 15 m

Answer: Biology

This is because the first two make no sense and physics is the study of matter and energy. Biology, however, studies the life of plants and animals, which can be used for renewable energy.

Explanation:

The rod can be in equilibrium only if the resultant force is 0 and the moment around any point of the rod must be equal to 0.

We have to take moments around the pivoted point.

Moment = Force × Perpendicular distance to the force

For the rod to be in equilibrium,

Clockwise moment - Anticlockwise moment = 0

Clockwise moment = Anticlockwise moment

The distance between pivoted point and the weight of rod = 50 cm - 30 cm = 20 cm

So 20 cm× 1.2 N produces a Clockwise moment

If Perpendicular distance between pivoted point and 2N load is x,

Anticlockwise moment = x × 2N

20 cm× 1.2N = 2N × x

x = 12 cm

So 2 N load is at 12 from the pivoted point.

From the left edge of the meter ruler, 2N load is at 30-12 cm distance

= 18 cm

Answer:

Where is the picture send again please

Explanation:

Answer:

Given: a projectile of initial launch velocity(V) and launch angle ∅ and no air resistance. At the maximum height, the projectile would have a zero contribution of speed from the vertical component(Vy) Therefore, if we say Vx=Vcos∅ is the only speed the projectile has at the instant of maximum height then we can replace Vx with 1/5V and write 1/5V=Vcos∅. Solving for the the launch angle ∅, gives Inverse Cos(1/5)=78.5 degrees.

Car speed = 40m/ hour

3 hours = 40 × 3 = 120m /hour

Answer:

120

Explanation:

if the car travels 40 in one hour , to find the speed in 3 hours multiply 40 x 3 which will give us 120

She is 1.0 m higher than she is when she started. The speed at which the woman must be running when she grabs the rope is 4.427 m/s

Suppose we consider the Figure 1 to be a right-angle triangle;

where;

∴

Using Pythagoras rule;

(hyp)² = opp² + adj²

5.0² = 3.0² + x²

x² = 25 - 9

x² = 16

x = √16

x = 4 m.

When she is directly over the far edge of the ravine, the height at which she is far higher than where she started is:

= 5cm - 4cm

= 1 cm

The speed at which the woman must be running when she grabs the rope can be determined by taking both the potential energy and kinetic energy of the system, which can be computed as:

Making the speed the subject of the formula, we have:

[tex]\mathbf{v = \sqrt{2gh}}[/tex]

[tex]\mathbf{v = \sqrt{2\times 9.8 \times 1.0}}[/tex]
