A PROJECTILE is any object upon which the only force is gravity, There is a vertical ACCELERATION CAUSED by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.purple you armYhave a bangastic day

Hybrid vehicles are called hybrids because they USE both a SMALL internal combustion engine (ICE) and an electric motor to obtain maximum power and FUEL ECONOMY with minimum emissions.Explanation:Hope its help you..

tion:The passengers in a bus TEND to FALL backward when it starts suddenly due to INERTIA as the passengers tend to remain in the STATE of rest while the bus starts to move. When the bus stops suddenly, PEOPLE fall forward because their inertia as they are in state of motion even when the bus has come to rest.Hope it helps :)

give three examples of chemical CHANGES. Explain whether each change is slow or FAST, reversible or IRREVERSIBLE, and man-made or naturaliExplanation:sach mai kutta hai sach BATAU maan kar RHA hai murder kar doovo tereko kyu pasata hai kya maja aata hai usse

� tendon - cordlike attachment � aponeurosis - thin flat sheet � fascia - thin flat sheets of connective tissues that wrap and bind parts of the body together � raphe - junction of two muscles at a band of connective TISSUE to FORM a line of fusion, such as the linea albaBasis for muscle contraction:� a muscle receiving no nervous stimulus is relaxed or in a resting state - soft shape RETAINED by surrounding collagen fibers � when nervous stimuli APPLIED beyond muscle�s threshold level, contraction results and tensile force is generated, constituting the active state � the attached bone and/or mass that must be moved represents the load - WHETHER a muscle actually contracts depends on the relative balance between the tensile force of contraction and the load to be moved (Fig. 10.6, p. 351)Major contractile characteristics of a muscle include how rapidly it reaches maximum tension and how long it can sustain this tensionTension and strength are directly related to the number of cross-bridges between muscle filaments

Time TAKEN to cover 20 KM at speed  5 km/hr = 4 hours∴ Fixed time = 4 hour - 40 MINUTES = 3 hour 20 minTime taken to cover  20 km at the speed 8 km/hr = 20/8 = 2 hours 30 minutes∴ Required time  = 3 hours 20 minutes - 2 hr 30 min=50 minutes

Ufff MERI crazy behna...tuje bohot kuch HAI kehna..pehle apne AAS paas waali cheezon me jo movement hai kya ho ra ye sb PTA kr

Dimensional FORMULA for [G]=[M−1L3T−2].the FINAL answer is, the dimensional formula for universal gravitation CONSTANT is [M−1L3T−2].

ral any dimension expressed as a vector has positive and negative directions.In Cartesian coordinate SYSTEMS the axes are all expressed as having positive and negative directions.TIME has past and future which is often expressed as negative and positive respectively.In BUILDINGS the height above GROUND is expressed as positive and below ground as negative.The directions are generally ARBITRARY and reversible (except perhaps for time) but the potential for directionality seems inherent and possibly intrinsic to dimensionality.How are you???

The TRIANGULAR law of vector addition : If two vectors are represented both in magnitude anddirection by two sides of a triangle TAKEN in same order, then the THIRD side will GIVE the magnitude of the resultant vector with direction in OPPOSITE order.

e are assuming CIRCULAR motion, LET r(t) = R·ur, where R is a constant (the radius of the circle) and ur is the unit vector pointing from the ORIGIN to the POINT mass. The direction of ur is described by θ, the ANGLE between the x-axis and the unit vector, measured counterclockwise from the x-axis.

4.5Explanation:MGH = WORK DONE by gravitythereforeM = work done/ghso by SOLVING it further we GET m= 4.5

answer is 1Explanation:I=v/R according to this r is 10OHM and VOLT is 10

a CERTAIN physical quintity P can be calculated using the relation P= ROOT ab square/ C to the power 4/5, where a,b and c are any physical quintity with 1%,0.5%,2.5% as maximum errors in their RESPECTIVE meausurment.

Mechanical advantage is the ratio of load to EFFORT of machine or we can SAY it is the ratio of output of machine to the input of the machine. ... Thus, the mechanical advantage of the machine is equal to the PRODUCT of its efficiency and VELOCITY ratio.Explanation:Mechanical advantage is the ratio of load to effort of machine or we can say it is the ratio of output of machine to the input of the machine. ... Thus, the mechanical advantage of the machine is equal to the product of its efficiency and Velocity ratio.

ated motion ACCELERATION, RATE at which VELOCITY CHANGES with time, in terms of both SPEED and direction.formula ️v/ ️u

- V = (50±5)V I = (5±1)A As we KNOW that,R = V/I Now PERCENTAGE error,% ∆R/R = (∆V/V + ∆I/I)×100% ∆R/R = (5/50 + 1/5)×100% ∆R/R = (1+2/10)×100% ∆R/R = 30% Hence,Error = % ∆R/R = 30%

The solids can be classified into conductors, insulators, and semiconductors depending on the distribution of electron energies in each atom. As an outcome of the small distances between atoms, the resulting INTERACTION amongst ELECTRONS, and Pauli's exclusion PRINCIPLE, ENERGY bands are formed in the solids.Explanation:HOPE IT HELPSPLEASE MARK ME AS BRAINLIAST

The number of PERIODS or CYCLES per second is called FREQUENCY. The SI UNIT for frequency is the hertz (Hz). One hertz is the same as one CYCLE per second.

Distance from P to end= 200mTotal distance to and fro=200+200=400mTime taken to and fro = 1min 40 SEC=(60+40)×2=200secExplanation:Average SPEED =Total distance/Total time =400/200=2m/secAverage VELOCITY =Total DISPLACEMENT/Total time=0/200= 0m/sec(here displacement =0 as the final change in POSITION is nil)

this is the ANSWER BRO SORRY for Bad drawing I hope you will understand

Momentum = m×vwhere, m = mass of BODY and, v = velocity of bodyso,momentum of given ques. = 1000 × 18 = 18000 kg-km/hr = 5000 kg-m/sec Mark as Brainliest, it really MOTIVATES!

Because pens can't function in zero gravityExplanation:NASA scientists realized that pens could not function in zero gravity. They therefore spent years and millions of taxpayer dollars developing a ballpoint pen that could put ink to paper without needing gravitational force to pull on the fluid.PENCILS may not have been the best choice anyway. The tips could flake or break off, drifting in microgravity where they might harm an ASTRONAUT or EQUIPMENT. And pencils are flammable—a characteristic NASA wanted to avoid in onboard objects after the APOLLO 1 fire.

Some versions of general relativity SUGGEST that time travel might only be possible in a region of SPACETIME that is warped a CERTAIN way, and hence time travelers WOULD not be ABLE to travel back to earlier regions in spacetime, before this region existed.
