A simple pendulum is 1.15 meters long and has a period of 6.29 seconds. The pendulum is on an unknown planet. What is the accele

Nastasia [14]

Answer:

The value of the acceleration of gravity of the Unknown Planet = 1.14 $\frac{m}{s^{2} }$

Explanation:

length of the pendulum (L)= 1.15 m

Time period (T)= 6.29 seconds

We know that time period of a simple pendulum is given by

⇒ T = 2 $\pi$ × $\sqrt\frac{L}{g}$

put the values in the above formula we get

⇒ T = 2 $\pi$ × $\sqrt \frac{1.15}{g}$

⇒ 6.29 = 2 $\pi$ × $\sqrt \frac{1.15}{g}$

By solving the above equation we get

⇒ g = 1.14 $\frac{m}{s^{2} }$

This is the value of the acceleration of gravity of the Unknown Planet.

The speed of a certain proton is 350 km/s. If the uncertainty in its momentum is 0.100%, what is the necessary uncertainty in it

Evgesh-ka [11]

Answer:

$\Delta x = 1.807 \times 10^{-10}m$

Explanation:

mass of proton, m = 1.67 x 10^-27 kg

speed of proton, v = 350 km/s = 350,000 m/s

Momentum of proton, p = mass x speed

p = 1.67 x 10^-27 x 350000 = 5.845 x 10^-22 kg m /s

uncertainty in momentum, Δp = 0.1 % of p

Δp = $\frac{0.1\times 5.845 \times 10^{-22}}{100}=5.845 \times 10^{-25}$

According to the principle

$\Delta x\times \Delta p \geq \frac{h}{2\pi }$

where, Δx be the uncertainty in position

$\Delta x\times 5.845 \times 10^{-25}= \frac{6.634 \times 10^{-34}}{2\times 3.14}$

$\Delta x = 1.807 \times 10^{-10}m$

When an object is put into a liquid, it experiences a buoyant force that is equal to the weight of the liquid the object displac

Anon25 [30]

Answer:

A) F = 1.8375 N, B) V = 1.25 10⁻⁴ m³, C) V= 1.25 10⁻⁴ m³

Explanation:

This exercise should select some values such as the weight of the block m=0.250 kg and the density of the liquid ρ = 500 kg / m³ (water); with these values answer the question, for this we use the static equilibrium relations.

Σ F = 0

F + B - W = 0

the expression for thrust is

B = ρ g V_liquid

A) the weight of the block is

W = m g

W = 0.250 9.8

W = 2.45 N

Let's look for the maximum push

V_body = V_liquid

B = 500 9.8 0.05³

B = 0.6125 N

we substitute

F = W - B

F = 2.45 - 0.6125

F = 1.8375 N

B) As the body is totally submerged, the volume of the liquid and the body are equal

V = l³

V = 0.05³

V = 1.25 10⁻⁴ m³

C) the volume of water displaced is equal to the volume of the body

V_liquid = 1.25 10⁻⁴ m³
