What two things determine an objects momentum

1 answer:

6 0

Momentum is defined as the the product of mass and velocity of an object.

$\boxed{ \bold{momentum= mass \times velocity}}$

So the two things on which determine an object's momentum is:

1. mass of the object

2. velocity of the object

Two particles, one with charge − 7.97 μC −7.97 μC and one with charge 7.75 μC, 7.75 μC, are 8.09 cm 8.09 cm apart. What is the m

mr Goodwill [35]

Answer:

Electric force, F = 84.93 N

Explanation:

Given that,

Charge on particle 1, $q_1=-7.97\ \mu C=-7.97\times 10^{-6}\ C$

Charge on particle 1, $q_2=7.75\ \mu C=7.75\times 10^{-6}\ C$

The distance between charges, d = 8.09 cm

To find,

The magnitude of the force that one particle exerts on the other.

Solution,

The electric force of attraction or repulsion is given by the formula as:

$F=\dfrac{kq_1q_2}{d^2}$

k is the electrostatic constant

$F=\dfrac{9\times 10^9\times 7.97\times 10^{-6}\times 7.75\times 10^{-6}}{(8.09\times 10^{-2})^2}$

F = 84.93 N

So, the magnitude of the force that one particle exerts on the other is 84.93 N.

A hungry 173173 kg lion running northward at 82.782.7 km/hr attacks and holds onto a 36.236.2 kg Thomson's gazelle running eastw

Galina-37 [17]

Answer:

the final speed after attack is 69.09 km/h

Explanation:

lion weight = 173 kg

running northward at 82.7 km/hr

weight of gazelle = 36.2 kg

running eastward at 57.4 km/hr

using momentum conservation along north direction

(173) × (82.7) = (173 + 36.2 ) × vₙ

vₙ = 68.38 km/h

using momentum conservation along east direction

36.2 × 57.4 = (173 + 36.2 ) × vₓ

vₓ = 9.93 km/h

$v = \sqrt{v^2_n+v^2_x} \\v = \sqrt{68.38^2+9.93^2}\\v=69.09 km/h$

hence the final speed after attack is 69.09 km/h

Hypertension is called "the silent killer" because __________.

Furkat [3]

Hypertension is called the silent killer because most patients with high blood pressure have no symptoms to alert them to the elevated pressure. But over time,high blood pressure increases the risk of serious problems such as stroke, congestive heart failure, heart attack, and kidney failure.
