A force of 10N was applied to the ball by the bowler.
What is a force?A force is any interaction that, when unopposed, will change the motion of an object. It can be a push or a pull. What are the Effects of Force?
Typically, motion can either be described as:
Change in speedChange in directionEffects of a forceForce can make a body that is at rest to move.It can stop a moving body or slow it down.It can accelerate the speed of a moving body.It can also change the direction of a moving body along with its shape and size.It is determined by the formula; F = ma
Where m = mass
a = acceleration
From the question;
m = 5kg
a = 2m/s2
F = ma
F = 5 x 2

the current in a certain ac circuit is independent of the frequency at a given voltage. which combination of elements is most likely to comprise the circuit?
A capacitor and a resistor in series. This is known as a low-pass filter, and it attenuates higher frequencies more than lower frequencies, so at a given voltage the current will not depend on the frequency.
What is frequency?
In physics, frequency is the amount of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time. After moving through a series of situations or positions and then returning to its initial position, a body in periodic motion is thought to have experienced one cycle or one vibration. See also simple harmonic motion and angular velocity.
The frequency is 2 per second if the period, or time interval, needed to complete one cycle as well as vibration is 1/2 second; it is 100 per hour if the period is 1/100 of an hour. In most cases, the frequency is equal to the period, or time interval, reciprocally, so frequency = 1/period = 1. (time interval).

What is sunscreen?
Sunscreen, also referred to as sunblock as well as sun cream, is a topical photoprotective product for the skin that primarily absorbs or, to a much lesser extent, reflects some ultraviolet (UV) radiation from the sun. This helps prevent sunburn and, more importantly, skin cancer. Lotions, sprays, hydrocolloids, foams, sticks, powders, as well as other topical products are all forms of sunscreen. Sunscreens are common additions to clothing, especially sunglasses, sunhats, and other types of photoprotective clothing (such as umbrellas). H.A. Milton Blake, an Australian chemist, created the first sunscreen in 1932 using a 10% concentration of the UV filter salol (phenyl salicylate).
Since they do not contain as many active ingredients, they are less likely to expire quickly. Additionally, because the sunscreen is in a spray form, it is less likely to be contaminated with bacteria or dirt, which can cause it to expire more quickly.

Because the output current of the first resistor flows into the input of the second resistor in a series circuit, the current through each resistor is equal. All of the resistor leads on one side of the resistors are connected together, as are all of the leads on the other side, in a parallel circuit.

a car is traveling with a speed of 20.0 m/s along a straight horizontal road. the wheels have a radius of 0.300 m. if the car speeds up with a linear acceleration of 1.50 m/s2 for 8.00 s, find the angular displacement of each wheel during this period.
The angular displacement of each wheel during this period will be 209 rad
Explain angular displacement
A body's angular displacement is the angle (measured in radians, degrees, or revolutions) by which a point rotates around a specific axis or center in a particular way. Because a body rotating about its axis experiences variable velocities and accelerations at all times, the motion cannot simply be considered as a particle motion (t).
We must first assume that the car's wheels are not slipping in relation to the pavement. If so, we can infer that the angular velocity and acceleration are given by
w = v/r = (20m/s)/(.300 m) = 6 rad/s
a = a/r = (1.5 m/s2)/(.300 m) = 5 rad/s2
Using this data, we can calculate the angular displacement by:
angular displacement = (6 rad/s)(8.00 s) + .5(5 rad/s2)(8.00 s)2
= 48 rad + 160 rad = 209 rad

What is kinetics?In this situation, we have a three-dimensional problem that kinematics can help us solve by determining the position, velocity, and acceleration of the body.
The vector, which is the ball's position in the air at time t,
p(t) = (60 i + 64 k) t + 1/2 (-6 j - 32 k) t ²
and its velocity is given by
v(t) = (60 i + 64 k) + (-6 j - 32 k) t
The time the ball is in the air is equal to the time it takes for the position vector's vertical (k) component to reach zero, so we solve,
64 t - 32/2 t ² = 0 ==> t = 0 OR t = 4
and so the ball is in the air for 4 s.
The ball has position vector.
p(4) = (60 i + 64 k) t + 1/2 (-6 j - 32 k) t ² = 240 i - 48 j

where T = 2Usin(theta)/g;
U is the ball's starting speed, which is 35 m/s.
The angle the ball makes with the horizontal is theta, which is equal to 45°.
The acceleration caused by gravity is g = 9.81 m/[tex]s^{2}[/tex]
Incorporating the provided data into the existing formula;
T = 35sin45°/9.81
T = 35×0.7071/9.81
T = 24.74/9.81
2.52 seconds later
2.23 seconds is the cannons' total flight time.

a proton has a mass of 1.67×10−27 kg . if the spring were to break, the α particle would disintegrate and the protons would fly off in opposite directions. what would be their ultimate speed?
The ultimate speed is 0.333× 10⁸ ms‐¹.
The proton mass is 1.67×10−27 kg. If the spring were to break, the alpha particles would collapse and the protons would fly in the opposite direction.
Calculation:-
Deuterons:= 0.333×108ms−1
m2=3.34×1027kgu2=0
Let v be the velocity of the combination
Then from momentum conservation
m1u1+ m2u2= (m1+m2)v
1.67×1027×108+3.34×1027
= ( 1.67+3.34)×10−27×v
binding velocity
v=1.67×10−27×1085.01×10−27
= 0.333×108ms−1
A proton is a stable subatomic particle with a positive charge of +1 e elementary charge, symbol p, H+, or 1H+. Its mass is slightly less than that of a neutron, 1836 times that of an electron (proton-to-electron mass ratio). Protons and neutrons, each with about one atomic mass unit, are collectively called "nucleons" (particles present in the nucleus)

ii)The most stable nucleus in terms of binding energy per nucleon is 56fe.
iii) The core of nuclear fission reactors consists of uranium enriched in 235u surrounded by a moderator which slows down the neutrons from the 235u.
What is Nucleus?This is referred to as the dense part which is present at the center of the atom and it comprises of particles such as proton and neutron. Iron -56 is referred to as the most stable nucleus because it has the lowest mass per nucleon of all nuclides.
Nuclear fusion is the process in which two light nuclei merge to form a single heavier nucleus and energy is generated as a result which is used by stars.

how fast must air blow across the top of the straw to draw water to the top of the straw? assume that the density of air is
The air blows across the straw's top at a speed of 122.79H m/s, causing water to collect there. To get water to collect at the straw's top, air is blown over it.
A moving object is said to be moving at a variable pace when it travels a varying distance at regular intervals of straw's top. The uniform speed determined by the ratio of the whole distance travelled by an object to the total amount of time it took to travel that distance is known as the average speed. Air blow straw's top are renowned to offer targeted, high-pressure output and are most ideal for automotive and industrial cleaning applications.
1/2*density* v = density*g*h
v = (density of b / 2*density*g*h)1/2
= (2*1000*9.8*h/1.3)\sv = 122.79h
