Answer:

at the highest point

Explanation:

velocity of a particle becomes minimum when the  particle projected halfway or from ground reaches its maximum height.

No matter what direction a projectile is traveling, its velocity
will be minimum at the highest point in its trajectory.

I just realized ... that's also true of an Earth satellite.

It takes a soccer player 3 seconds so reduce his speed to 3.1 m/s. What is the magnitude of his acceleration?
Volgvan
Acceleration =change in velocity/change in time.
So final speed minus initial velocity/time

Convert gravitational potential energy to kinetic energy.
Digiron [165]

Answer:

1.7 J

Explanation:

The energy carried by a single photon is given by

E=hf

where h is the Planck's constant and f is the frequency of the photon.

The photon of our exercise has a frequency of f=1.7 \cdot 10^{17} Hz, therefore its energy is

E=hf=(6.63 \cdot 10^{-34}Js)(1.7 \cdot 10^{17} Hz)=1.1 \cdot 10^{-16} J

How much kinetic energy does a system containing 3 moles of an ideal gas at 300 K possess? What is the heat capacity at constant
ElenaW [278]

Answer:

1. K.E = 11.2239 kJ ≈ 11.224 kJ

2. C_{V} = 37.413 JK^{- 1}

3. Q = 10.7749 kJ

Solution:

Now, the kinetic energy of an ideal gas per mole is given by:

K.E = \frac{3}{2}mRT

where

m = no. of moles = 3

R = Rydberg's constant = 8.314 J/mol.K

Temperature, T = 300 K

Therefore,

K.E = \frac{3}{2}\times 3\times 8.314\times 300

K.E = 11223.9 J = 11.2239 kJ ≈ 11.224 kJ

Now,

The heat capacity at constant volume is:

C_{V} = \frac{3}{2}mR

C_{V} = \frac{3}{2}\times 3\times 8.314 = 37.413 JK^{- 1}

Now,

Required heat transfer to raise the temperature by 15^{\circ} is:

Q = C_{V}\Delta T

\Delta T = 15^{\circ} = 273 + 15 = 288 K

Q = 37.413\times 288 = 10774.9 J = 10.7749 kJ

The volume of a ball was measured at 500.0 cm3, and its mass was measured to be 404.2 g.
KonstantinChe [14]

Answer:

0.8084g/cm³

Explanation:

For calculating density, mass is divided by volume.

Its units is commonly in grams per cubic centimeters.

Therefore,

density= mass/volume

= 404.2/500

=0.8084g/cm³
