Answer:

If they lift less weight, each time then they will grow stonger.

Whereas if you lifted more weight than them, and you couldn't do it then that means they are actually stronger than you.

I hope this helps!!!!

If someone lifts less weight that is force due to gravity than you many times than they are powerful.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Answer:

x=10.39 m/s

y = 6 m/s

Explanation:

Components of a Vector

A vector can be expressed in several forms, including the rectangular and the polar form.

The rectangular form uses the x-y coordinates of the vector, being the right and up directions considered as positive.

The polar form uses the magnitude r and the angle it forms with the positive x-direction.

Given the polar form (r,θ), we can calculate the rectangular coordinates as follows:

[tex]x=r\cos\theta\\[/tex]

[tex]y=r\sin\theta[/tex]

The soccer ball is kicked with an initial speed of v=12 m/s and an angle of 30 degrees. Thus the horizontal and vertical components are:

[tex]x=12~m/s\cos 30^\circ[/tex]

x = 10.39 m/s

[tex]y=12~m/s\sin 30^\circ[/tex]

Answer:

Tension in the 55 degree cable  = 110.56 N

Tension in the 28.5 degree cable = 72.16 N

Explanation:

Decompose the two tensions T1 (on left cable) and T2(on right cable) in vertical and horizontal components using trigonometric functions sine and cosine. Then balance the forces in the vertical and in the horizontal as shown below:

Horizontal components acting on net horizontal force:

T1 cos(55) =T2 cos(28.5)

then  T1 = T2 (cos(28.5) / cos(55))

Vertical components acting on net vertical force:

T1 sin(55) + T2 sin(28.5) = 125

Now replace T1 with T2 (cos(28.5) / cos(55)) in the last equation:

T2 (cos(28.5) * sin(55)/ cos(55)) + T2 * sin(28.5) = 125

T2 ( cos(28.5) * tan(55) + sin(28.5)) = 125

solving for T2 we get: 72.16 N

now we use this T2 result in the substitution equation:

T1 = T2 (cos(28.5) / cos(55))

T1 = 110.56 N

Answer:

Diagram A

Explanation:

When an object is travelling in a circular path it has an acceleration called centripetal acceleration, even if it is moving with uniform speed. This acceleration is attributed to the object due to change in the direction of velocity at every instant during the motion.

The direction of the velocity of the object is tangent to the circular path at every instant and if the object beaks free of the circular motion, such as breaking of the string, then it will go in the direction tangent to the circle at that instant. Hence, the diagram that best shows the direction ball will travel is:

a. The limit of resolution on this microscope is approximately 1254nm.

b. Two points that are 300nm apart will blur into one and cannot be distinguished as separate using this microscope.

The formula for the limit of resolution (d) is given by:

d = (0.61 × λ) / NA

where λ is the wavelength of light and NA is the numerical aperture.

a. To find the limit of resolution:

Given:

Wavelength of light (λ) = 520nm

Numerical aperture of the low-power objective lens (NA) = 0.25

Substituting these values into the formula, we have:

d = (0.61 × 520) / 0.25

d = 1254nm

Therefore, the limit of resolution on this microscope is approximately 1254nm.

b. To determine if two points 300nm apart can be distinguished:

Given:

Separation between the points (d) = 300nm

Since the separation between the points (300nm) is smaller than the limit of resolution (1254nm), the two points will blur into one and will not be distinguishable as separate entities.

In conclusion:

a. The limit of resolution on this microscope is approximately 1254nm.

b. Two points that are 300nm apart will blur into one and cannot be distinguished as separate using this microscope.

Answer:

19.62 m/s

34.335 m/s

1.75 m

Explanation:

v = Final velocity

u = Initial velocity = 0

a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

t = Time taken = 2 s

From the equations of linear motion we have

[tex]v=u+at\\\Rightarrow v=0+9.81\times 2\\\Rightarrow v=19.62\ \text{m/s}[/tex]

The speed of the object after 2 seconds is 19.62 m/s

t = 3.5 s

[tex]v=u+at\\\Rightarrow v=0+9.81\times 3.5\\\Rightarrow v=34.335\ \text{m/s}[/tex]

The velocity of the object when it strikes the ground is 34.335 m/s.

[tex]v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{34.335-0}{2\times 9.81}\\\Rightarrow s=1.75\ \text{m}[/tex]

In order to calculate the tangential speed of the satellite,  Enrique should do first converted the orbital period to seconds. The correct option is b.

Any item moving along a circular path has a linear component to its speed called tangential velocity. An object's velocity is always pointed tangentially when it travels in a circle at a distance r from the center. Tangential velocity is the name given to this.

Satellites can go over the Earth's North and South Poles, orbit the equator, or travel anywhere in between. They travel thousands of miles into space or only a few hundred miles above the surface of the Earth to perform their orbits. Enrique has given:

r=3.8 x 108 m

Answer:

Frequency is the number of wavelengths, which is measured in hertz.

Explanation:

I have my ways ;)

The relationship between the terms “frequency,” “wavelength,” and “hertz" is that frequency is the number of wavelengths, which is measured in hertz.

The wavelength is described as the distance between two points on a wave having the same phase. It is also defined as the distance between two successive maxima or minima of the waveform.

The frequency of a wave is the measure of the number of wavelengths completed in one second and it is measured in Hertz (Hz).

The frequency is also the reciprocal of the time period of the wave, which is the time taken to complete one wavelength.

Therefore, frequency is the number of wavelengths, which is measured in hertz.

Explanation:

The order of steps in the energy conversion during the production of electricity from wind turbine are as follows:

1. First of all, the wind transmits its kinetic energy to the turbine blades by striking the blade.

2. The turbine blades are connected to a generator. The kinetic energy of the turbine blades is utilized to turn the generator shaft.

3. The generator then converts the kinetic energy of the blades into electricity.

Answer:

1.1 x 10⁻⁵m³

Explanation:

Given parameters:

Weight in air  = 11.29N

Weight in water  = 9.190N

Density of gold  = 19320kg/m³

Unknown:

Volume of the secret cavity = ?

Solution:

To solve this problem, we need to find the mass of the secret cavity.

Weight of the cavity  = Weight of sculpture in air  - Weight of sculpture in water

 Weight of cavity  = 11.29N  -  9.190N = 2.1N

 Weight  = mass x acceleration due to gravity

        Mass  =[tex]\frac{2.1}{9.8}[/tex]   = 0.2kg

So;

 Volume of substance can be determined from the density.

 Density  = [tex]\frac{mass}{volume}[/tex]  

   Volume  = [tex]\frac{mass}{density}[/tex]  

 Now insert the parameters and solve;

  Volume  = [tex]\frac{0.2}{19320}[/tex]   = 1.1 x 10⁻⁵m³

The parachutist is falling at a constant speed, so the net force acting on them is zero. The only forces acting on the parachutist are their own weight (magnitude w, pointing downward) and the drag produced by the parachute (mag. d, pointing upward). By Newton's second law,

d - w = 0

or d = w. The parachutist's weight is

w = (70 kg) (9.80 m/s²) = 686 N

so that the total upward force is also 686 N.

Answer:

m = 15.15 kg

Explanation:

Newton's Second Law of motion states that when an unbalanced force is applied on a body, an acceleration is produced in it in the direction of force. The component of force along the horizontal direction here, will be given by the Newton's Second Law as:

Fx = ma

F Cosθ = ma

where,

F = Magnitude of Force = 85 N

θ = Angle with horizontal = 27°

m = mass of object = ?

a = acceleration of object = 5 m/s²

Therefore,

85 N Cos 27° = m(5 m/s²)

m = 75.73 N/5 m/s²
