You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is negligible friction between your feet and the ice. A friend throws you a 0.400-kg ball that is traveling horizontally at 10.0 m/s. Your mass is 70.0 kg. (a) If you catch the ball, with what speed do you and the ball move after ward
Answer:
0.38m/s
Explanation:
Given data
M1= 0.4kg
U1= 10m/s
M2= 70kg
U2= 0m/s
The system experiences an inelastic collision, the expression for inelastic collision is
M1U1+ M2U1= (M1+M2)V
Subsitute
0.4*10+ 70*0= (0.4+10)*V
4= 10.4V
4=10.4V
V= 4/10.4
V=0.38m/s
Hence the common velocity is 0.38m/s
Un vehiculo se desplaza con movimiento rectilio uniforme. Sabiendo que recorre 90 km en 3 horas. Averiguo la velocidad en m/s.
Answer:
Velocidad = 500 m/s
Explanation:
Dados los siguientes datos;
Distancia = 90 km
Tiempo = 3 horas
Conversión;
Por distancia:
1 kilómetro = 1000 metros
90 kilómetros = 90 * 1000 = 90,000 metros
Para el tiempo:
1 hora = 60 segundos
3 horas = 60 * 3 = 180 segundos
Para encontrar la velocidad en m/s;
Matemáticamente, la velocidad viene dada por la ecuación;
[tex] Velocidad = \frac {distancia} {tiempo} [/tex]
Sustituyendo en la fórmula, tenemos;
Velocidad = 90000/180
Velocidad = 500 m/s

Two Brothers are playing soccer on the beach. One brother kicks the ball really hard and the ball lands in the water, about 50 meters from the beach. They wonder if the ball will float back to the beach.
Answer:
Due to wind and waves of water.
Explanation:
They wonder that the ball will float back to the beach because of the wind and the waves of the water. The wind blows towards the beach which moves the water in the form of waves towards the beach so if the ball lands in the water, it will floats on the surface of water and move towards the beach with the help of wind and waves of the sea. The ball floats on the water due to its lighter weight and lower density as compared to water.

if the voltage across a 12 ohm resistor is 4.0 volts. the current through the resistor is?
Answer:
Current = 0.33 Amperes
Explanation:
Given the following data:
Resistance = 12 ohm
Voltage = 4 v
To find the current;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Voltage = current * resistance
Substituting into the formula, we have;
4 = current * 12
Current = 4/12
Current = 0.33 Amperes
An element in a similar period to carbon would be

The Grand Canyon is more than 400 km long and in some places almost 2 km deep. Which model best represents the main process that formed the Grand Canyon?
Answer: Diagram A
Explanation:
The Grand Canyon was created by the constant flow of the Colorado river which physically broke down the rock for billions of years. It then carried off the rock as it flowed and as it kept doing this, the canyon kept getting deeper and deeper.
This is what is described in the first diagram. The water from the faucet is carrying the soil along with it much like the Colorado did to the rocks of the Grand Canyon.

B.
Machine 1’s mechanical advantage is greater, which means that this machine can move faster than Machine 2.
C.
Machine 2’s mechanical advantage is greater, which means that this machine can do more work with less force than Machine 1.
D.
Machine 2’s mechanical advantage is greater, which means that this machine can move faster than Machine 1.
Answer:
b
Explanation:
Machine 2’s mechanical advantage is greater, which means that this machine can do more work with less force than Machine 1.
Mechanical advantageThe term mechanical advantage is the ratio of the radius of wheel to the radius of the axle for a wheel and axle system.
The true statement about the two machines that were compared; 1 and 2 is that, machine 2’s mechanical advantage is greater, which means that this machine can do more work with less force than Machine 1.

S. Explain the washing effects of detergents of soap and why detergents in warm water washes greasy
clothes even better
Answer:
Soaps and detergents are made from long molecules that contain a head and tail the detergent molecules also help to make the washing process more effective by reducing the surface tension of the water. Surface tension is the force which helps a blob of water on a surface hold its shape and not spread out.

Why is diffraction used in soil profiles?
Answer:X-ray diffraction (XRD) is the technique most heavily relied on in soil mineralogical analysis. X-ray diffraction is a technique that provides detailed information about the atomic structure of crystalline substances. It is a powerful tool in the identification of minerals in rocks and soils.
Explanation:
XRD is used to identify the minerals composing clay-rich, hydrothermally altered rocks that occur on several Cascade volcanoes. Such rocks are believed to play an important role in the generation of large landslides and mudflows. XRD is used to analyze saline minerals, including borates.

An engine does 1421000 J of work to lift a beam 145 meters. How much force was exerted to lift the beam.
1566N
9800N
20445 N
50000N
Answer:
9800 N
Explanation:
applying,
W = Fd.................. Equation 1
Where W = work done by the engine, F = Force exterted to lift the beam, d = distance.
make F the subject of the equation
F = W/d............... Equation 2
From the question,
Given: W = 1421000 J, d = 145 meters.
Substitute these values into equation 2
F = 1421000/145
F = 9800 N

Newton's First Law state
For every action there is an equal and opposite reaction.
An object in motion stays in motion unless acted upon by an unbalanced force.
Gravity acts on all objects that have mass.
Force= mass x acceleration
Answer: an object in motion stays in motion unless acted upon by an unbalanced force
Explanation: this is Newton’s first law of motion, which states that an object, whether in a moving or resting state, will continue to stay in that state unless there is an unbalanced force that changes that state. For a moving object, an example would be friction worth the ground. For a resting object, an example would be the force of a push.

Which of the following is an example of uniform circular motion?
A. Swinging on a swing
B. Spinning on a merry-go-round
C. Sliding down a slide
D. Bouncing on a trampoline
Answer:
B
Explanation:
First narrow answers to CIRCULAR motion.
Only A and B have circular motion.
Second look at the keyword UNIFORM. A swing does not have uniform motion because it will accelerate due to gravity and have the most velocity at the bottom of the swing.
Therefore, it must be B.
