Answer: An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion

A Hooke's law bowstring is stretched x meters until a force of f newtons is applied, and then held. By what factor will the elas

Liono4ka [1.6K]

The elastic potential energy increases by a factor of 9

Explanation:

The elastic potential energy of a bowstring is given by

$E=\frac{1}{2}kx^2$ (1)

where

k is the spring constant

x is the elongation of the bowstring

Hooke's law states the relationship between the force applied and the elongation of an elastic object:

$F=kx$

where

F is the force applied

x is the elongation

We can rewrite it as

$x=\frac{F}{k}$

And substituting into (1),

$E=\frac{1}{2}k(\frac{F}{k})^2=\frac{F^2}{2k}$

In this problem, the force applied to the bowstring is tripled,

F' = 3F

So the final elastic potential energy is:

$E'=\frac{(3F)^2}{2k}=9(\frac{F^2}{2k})=9E$

So, the elastic potential energy increases by a factor of 9.

The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). If an object’s mas

lina2011 [118]

You just told us that Weight = (mass) x (gravity),
and that mass=10kg and gravity = 9.8 m/s².

All we need to do is write those numbers in place of the letters.

Weight = (10 kg) x (9.8 m/s²) = <em>98 newtons</em>.

Among the largest passenger ships currently in use, the Norway has been in service the longest. The Norway is more than 300 m lo

Answer:

$6.33\times 10^8\ kg\cdot m/s$

Explanation:

Mass of the ship (m) = 6.9 × 10⁷ kg

Speed of the ship (v) = 33 km/h

First, let us convert the speed from km/h to m/s using the conversion factor.

We know that, 1 km/h = 5/18 m/s

So, 33 km/h = $33\times \frac{5}{18}=9.17\ m/s$

Now, we know, the momentum of an object only depends on its mass and speed. Momentum is independent of the length of the object.

So, here, length of the ship doesn't play any role in the determination of the momentum.

Magnitude of momentum of the ship = Mass × Speed

= $(6.9\times 10^7\ kg)(9.17\ m/s)$

= $6.33\times 10^8\ kg\cdot m/s$

Therefore, the magnitude of ship's momentum is $6.33\times 10^8\ kg\cdot m/s$ .

The unit for acceleration is always

Mazyrski [523]

Explanation:

Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. ... The quicker you turn, the greater the acceleration.
