Can an object have both kinetic energy and gravitational potential energy? Explain.
Answer:
Yes
Explanation:
An object can be moving (have kinetic energy) and be elevated above the ground at the same time (and also have potential energy).
Yes an object can be moving have kinetic energy and be elevated above the ground at the same time and also have potential energy.
What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. Following work, energy is transmitted to the item, which causes it to move at a new, constant speed. An object can store energy as the result of its position is potential energy.
An object can be moving have kinetic energy and be elevated above the ground at the same time and also have potential energy.

How do volcanos effect ecosystems? in ur own words please!!
Answer:
well i guess i can try...
Explanation:
Volcanoes are a dangerous natural occurance that can greatly effect any ecosystems. There are various effects of volcanoes such as, lava flows, volcanic landslides, mud-flows, and ash flows, which generally result in total obliteration of any ecosystem in their path, they can also have long term beneficial effects to the environment. One of these long term effects are, the creation of some of the most nutrisous, and fertile soil on earth, causing healthy plants to grow.

Answer:
8.70 s
Explanation:
Given (in the y direction):
v₀ = 2.38 m/s
v = 0 m/s
a = 0.310 sin (-62.0°) m/s²
Find: t
v = at + v₀
0 m/s = (0.310 sin (-62.0°) m/s²) t + (2.38 m/s)
t = 8.70 s
If a rocket is launched with a velocity of 8,000 m/s, how high does it rise?
If a rocket of mass 117 kg is launched with a velocity of 800 m/s, so, the height is 32000m.
What is Kinetic energy?Kinetic energy is defined as the energy possessed by an object due to its motion that can be transferred between objects and converted into other forms of energy. It can be expressed as:
[tex]K.E.= 1/2 mv^2[/tex]
For above given information,
m is the mass which is 117kg
v is the velocity which is 8000m/s
So,
K.E.= [tex]1/2 (117)* (8000)^2[/tex]= [tex]3.744*10^7[/tex] Joules
So, we assume kinetic energy is equal to gravitational potential energy
G.P.E.= mgh
where, g is the gravitational strength which is 10N/kg for Earth
So,
[tex]3.744*10^7= (117).(10). h\\h= 3.744*10^7/1170\\h= 32000m[/tex]
So, the rocket of mass 117 kg is launched with a velocity of 800 m/s, so, the height is 32000m.

Answer:
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

Car #1 has a mass of 1000 kg and moves with a velocity of 10 m/s north.
Car #2 has a mass of 500 kg and moves with a velocity of 10 m/s north.
Compare and contrast Car #1 and Car #2.
A.
Car #1 has 2-times the momentum as Car #2
В.
Car #1 has 4-times the momentum as Car #2
Car #2 has 2-times the momentum as Car #1
D.
Car #2 has 4-times the momentum as Car #1
Answer:
A. Car #1 has 2-times the momentum as Car #2
Explanation:
Momentum is defined as the product of mass and velocity:
[tex]P = mv[/tex]
where,
P = Momentum
m = mass
v = velocity
FOR CAR # 1:
m = 1000 kg
v = 10 m/s
Threfore,
[tex]P_1 = (1000\ kg)(10\ m/s)\\P_1 = 10000\ N.s[/tex]
FOR CAR # 2:
m = 500 kg
v = 10 m/s
Threfore,
[tex]P_2 = (500\ kg)(10\ m/s)\\P_2 = 5000\ N.s[/tex]
Dividing both momentums:
[tex]\frac{P_1}{P_2} = \frac{10000\ N.s}{5000\ N.s}\\\\P_1 = 2P_2[/tex]
Therefore, the correct option is:
A. Car #1 has 2-times the momentum as Car #2

A 2 kg ball of clay moving at 35 m/s strikes a 10 kg box initially at rest. What is the velocity of the box after the collision?
Answer:
V = 5.83 m/s
Explanation:
Given that,
Mass of a ball of a clay, m = 2 kg
Initial speed of the clay, u = 35 m/s
Mass of a box, m' = 10 kg
Initially, the box was at rest, u' = 0
We need to find the velocity of the box after the collision. Let V be the common speed. Using the conservation of momentum to find it.
[tex]mu+m'u'=(m+m')V\\\\V=\dfrac{mu+m'u'}{(m+m')}\\\\V=\dfrac{2\times 35+10\times 0}{2+10}\\\\V=5.83\ m/s[/tex]
So, the velocity of the box after the collision is equal to 5.83 m/s.

Thermal conductivity of a material is given as 129Btuft–¹ h–¹°F–¹.Calculate this thermal conductivity in Jm–¹s–¹°C–¹(Given: 1Btu=1055J;0.3048m=1ft; and 1 °F= (5/9)°C)
Answer:
223.25 [tex]$\text{Jm}^{-1}\text{s}^{-1}^\circ\text{C}^{-1}$[/tex]
Explanation:
The thermal conductivity of an object is defined as the measure or the ability of the object to transfer heat or conduct heat through its body.
In the context, the thermal conductivity of the material is given as
[tex]$=129 \text{ Btu ft}^{-1}\text{h}^{-1}^\circ\text{F}^{-1}$[/tex]
And it is given that :
1 Btu = 1055 J
1 ft = 0.3048 m
[tex]$1^\circ F = \frac{5}{9}^\circ C$[/tex]
We know that 1 h = 3600 s
So the thermal conductivity of the material in [tex]$\text{Jm}^{-1}\text{s}^{-1}^\circ\text{C}^{-1}$[/tex] is :
Thermal conductivity :
[tex]$=\frac{129 \text{ Btu}}{1 \text{ ft }\times \text{1 h}\times 1^\circ\text{F}}$[/tex]
[tex]$=\frac{129 \times 1055 \text{ J}}{0.3048 \text{ m} \ \times 3600 \text{ s}\ \times \frac{5}{9}^\circ \text{C}}$[/tex]
= 223.25 [tex]$\text{Jm}^{-1}\text{s}^{-1}^\circ\text{C}^{-1}$[/tex]

Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities. Determine the radius of their circular path.
Answer:
r = 0.0548 m
Explanation:
Given that,
Singly charged uranium-238 ions are accelerated through a potential difference of 2.20 kV and enter a uniform magnetic field of 1.90 T directed perpendicular to their velocities.
We need to find the radius of their circular path. The formula for the radius of path is given by :
[tex]r=\dfrac{1}{B}\sqrt{\dfrac{2mV}{q}}[/tex]
m is mass of Singly charged uranium-238 ion, [tex]m=3.95\times 10^{-25}\ kg[/tex]
q is charge
So,
[tex]r=\dfrac{1}{1.9}\times \sqrt{\dfrac{2\times 3.95\times 10^{-25}\times 2.2\times 10^3}{1.6\times 10^{-19}}}\\\\r=0.0548\ m[/tex]
So, the radius of their circular path is equal to 0.0548 m.
How does the Coriolis effect influence the direction of the Trade Winds in the Northern Hemisphere? Does it have the same effect in the Southern Hemisphere?
Answer:
Part A
Coriolis effect is used to describe how objects which are not fixed to the ground are deflected as they travel over long distances due to the rotation of the Earth relative to the 'linear' motion of the objects
Due to the Coriolis effect the wind flowing towards the Equator from high pressure belts in the subtropical regions in both the Northern and Southern Hemispheres are deflected towards the western direction because the Earth rotates on its axis towards the east
Part B
In the Northern Hemispheres, the winds are known as northeasterly trade winds and in the Southern Hemisphere, they are known as the southeasterly trade wind. Therefore, Coriolis effect has the same effect on the direction of the Trade Winds in the Southern Hemisphere as it does in the Northern Hemisphere
