:- a) We know that the legs carry the weight of the body in the normal position DUE to gravity pull. The astronaut in space is in weightless state. Hence, swollen feet may not affect his working.(b) In the condition of weightless, the face of the astronaut is expected to get more supply. Due to it, the astronaut may develop swollen face. As eyes, ears,noes, mouth etc, are embedded in the face , hence swollen face may effect to great extent the seeing/hearing/smelling/eating capabilities of the astronaut in space.(c) Headache is due to MENTAL strain. It will persist WHETHER a person is an astronaut in space or he is on EARTH. It means headache will have the same effect on the astronaut as on a person on earth.(d) Space also has orientation. We also have the frames of reference in space. Hence, orientational problem will affect the astronaut in spacemark as a brainleast plz

I×R 2 = 0.4 × R R = 2÷0.4 R = 5 ohm(ii) when we say thee bolb is GLOWING it means that electricity is passing through the filament and this raises the temperature of filament. So, The RESISTANCE of a bulb INCREASES as the temperature of its filament increases.

a. pendulum C vibrates with smaller amplitude. SINCE pendulum D and A are of same length the vibrate with the same amplitudes.b. the natural frequency of Pendulum B is EQUAL to the frequency of vibration of Pendulum A since both are of equal length. so, the forced vibration caused in pendulum B are in resonance with vibrations of Pendulum A. on the other HAND the natural frequency of Pendulum C is higher while of D is smaller than that of Pendulum A. vibrates with the same frequency of Pendulum A bit smaller amplitude due to forced vibration

(E)EXPLANATION:both A and R are TRUE,R is CORRECT explanation for A

Interference occur due to interaction between PRIMARY WAVEFRONTS originating from two COHERENT SOURCES . But diffraction is the RESULT of interaction between two secondary wavelets originating from two different points of same wavefront.

By 1 kg WT = 10 N it means g = 10 m/s²Pressure = Force / Area in contact with ground= mg / A1.Pressure = (2.5 kg × 10 m/s²) / (10 cm × 5 cm × 10^-4 m²/cm²)= 5000 pascals= 5 kilo pascals2.Pressure = (2.5 kg × 10 m/s²) / (5 cm × 2 cm × 10^-4 m²/cm²)= 25000 pascals= 25 kilo pascals

or Resistance. ... Resistance is DEFINED as the opposition to the flow of ELECTRICAL current through a conductor. It's important to point out that conductivity and resistivity (the PROPERTY that determines final resistance) are INVERSELY proportionaHope it helps you ItzRiya✌️

n “a shunt” is a conductive component to be connected in parallel with ANOTHER device, commonly a meter movement, to share the current FLOW, ordinarily to ALLOW measurement of a higher range of current. HOPE it helps you ItzRiya✌️

hml=2mA=2m²R=RHO*l/A512=rho*2/2therefore, rho(RESISTIVITY)=512

a is DEPICTING OHM's LAW

e wire is STRETCHED to double the length , the area of CROSS section gets reduced to HALF. So when the wire is stretched to 2 times , the resistance multiplies by four times.____________________________________Information about resistance :Resistance is directly proportional to the length of the wire.Resistance is inversely proportional to the area of cross section of the wire

Because THERMOMETER is filled with Mercury which EXPAND and CONTRACT on fixed TEMPERATURE

20 C of CHARGE is flowing through the ammeter.Explanation:CURRENT flowing = 2 Atime = 10 s.Current = Charge/time         2 = Charge / 10Charge = 2 * 10Charge = 20 C (coulumb)

Both these types of MOTION have STATES of EQUILIBRIUM associated with them. An object is in translational equilibrium when the SUM of all the external forces acting on the object equals ZERO. ... In rotational equilibrium, an object either will not be moving or moving at a constant angular velocity.

1: Interference is due to the interaction of light coming from two different WAVEFRONTS originating from the same source. 1:Diffraction is due to interaction of light coming from different parts of the same wavefront. 2:Interference fringes are of the same width. 2:Diffraction fringes are not of the same width.3: Interference occur due to interaction between primary wavefronts originating from two coherent sources .3: diffraction is the result of interaction between two secondary wavelets originating from two different points of same wavefront. 4:interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude. 4:diffraction phenomenon is described as the apparent bending of waves around small OBSTACLES and the spreading out of waves past small openings.5: example, the CLOSELY spaced tracks on a CD or DVD act as adiffraction grating to form the familiar rainbow pattern seen when LOOKING at a disc.5:examples of interference is demonstrated by the light reflected from a film of oil floating on water. Another example is the thin film of a soap bubble, which reflects a spectrum of BEAUTIFUL colors when illuminated by natural or artificial light sources.

An electric current is the rate of flow of electric charge PAST a point or region. An electric current is SAID to EXIST when there is a net flow of electric charge through a region. In electric circuits this charge is often CARRIED by ELECTRONS moving through a wire.

ocouple is comprised of at least two metals joined TOGETHER to form two JUNCTIONS. ONE is connected to the body whose temperature is to be measured; this is the hot or measuring junction. The general circuit for the working of thermocouple is shown in the figure 1 above. It comprises of two dissimilar metals, A and B. These are joined together to form two junctions, p and q, which are MAINTAINED at the temperatures T1 and T2 RESPECTIVELY.
