I believe it would be a hot day in January, because deer like the cold. So if the snow melted and it would be really hot like summer, it would affect deer and other animal life.

The way it'd affect the climate is it could possibly affect snow. Maybe the next couple of days or weeks would be hot and when it is starting to get colder, it could not snow again for a long or short period of time

A 7.91g bullet is fired into a 1.52-kg ballistic pendulum initially at rest and becomes embedded in it. The pendulum subsequentl

Stella [2.4K]

Answer:

Explanation:

By law of conservation of momentum:

momentum before collision = momentum after collision

$m_{1} u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2\\ m_1 = mass of bullet\\u_1 = initial speed of bullet\\m_2 = mass of pendulum\\u_2 = initial speed of pendulum\\v_1 = final speed of bullet\\v_2 = final speed of pendulum$

Initial speed of bullet is unknown whereas initial speed of pendulum will be zero as it was at rest.

Final speed of bullet and pendulum will be equal as bullet is embedded in pendulum and both moves together a vertical distance of 6.89cm.

Using third equation of motion:

$2 a S = v_{f}^2 - v_{i}^2$

where:

$a = -g = acceleration due to gravity = 9.8 m/s^2 ( for vertical motion)\\S = h = 6.89cm = Vertical height or distance it covers\\v_f = final speed = 0 (after covering 6.89cm)\\v_i = initial speed (unknown)$

Thus by placing values $v_i = 1.1620 m/s$

this speed will be final speed of collision for the calculation of initial speed of bullet.

Putting values:

$(7.91) * x + (1.52*10^3) * 0 = (7.91 + 1.52*10^3) * 1.162\\7.91 x = 1775.431\\x = 224m/s$

This 224m/s = 0.224Km/s which is closest to D

9. Batman (mass=91 kg) jumps straight down from a bridge into a boat (mass=510 kg) in which a criminal is fleeing. The velocity

Ierofanga [76]

Answer:

V = 9.33 m/s

Explanation:

Given that,

Mass of the batsman, $m_1=91\ kg$

Mass of the boat, $m_2=510\ kg$

Initial speed of the boat, v = 11 m/s

Let V is the velocity of the boat after Batman lands in it. The net momentum of the system remains constant. Using the conservation of linear momentum to find it as :

$510\times 11=(91+510)V$

$V=\dfrac{510\times11}{(91+510)}$

V = 9.33 m/s

So, the velocity of the boat after Batman lands in it 9.33 m/s. Hence, this is the required solution.

TiliK225 [7]

Answer:

Only 9% weaker

Explanation:

Because this is where most stuff that people do in space takes place. So, um, here we're at a radius of the earth plus 300 kilometers. You may already be seeing why this isn't going to have much effect if this were except the 6.68 times, 10 to the sixth meters. And so the value of Gout here. You know, Newton's gravitational constant times, the mass of the Earth divided by R squared for the location we're looking at. And so this works out to be 8.924 meters per second squared, which is certainly less than it is at the surface of the earth. However, this is only 9% less than acceleration for gravity at the surface. So the decrease in the gravity gravitational acceleration of nine percent not really going toe produces a sensation of weightlessness.
