There is a drag force that opposes a person's motion while they are moving through a fluid, whether it be air or liquid. Range of motion is constrained by the drag force. Drag force is overcome by the suits. The drawback is overheating.

A bodysuit's main function is to give you support and a seamless tuck-in so you may dress comfortably and easily. Bodysuits can be skin-tight or loose, and because of the tension they create from the shoulders to the crotch, they can embrace your curves and serve as the ideal foundation for whichever bottom you choose.

They can be warm and tight or very thin - useful for warmth - or even be very light (say, 60g), cooling underwear. They are typically elastic and stretchy. They can serve as both underwear and outerwear, but a pair of trousers, pants, or a skirt must be worn below.

Benefits include being thin, warm or cooling, extremely snug, occasionally shapewear, suitable for layering, and warm without bulk (you can get a big deal from a 60g torso garment). fitting in.

The area below the force curve on a force versus time graph is known as the impulse.

The concept of "impulse" refers to how much of an impact a force has over time. The cricket batsman striking the ball is one of the most well-known and frequently used illustrations. The bat significantly changes the ball's trajectory despite making contact with it for a relatively brief period and launching a bicycle. Everyone occasionally makes rash decisions, particularly when we're young. In general, as we get older, we learn to control our urges. It might or might not be a sign of a problem.

Moment of momentum, which describes the rotating inertia of a system moving about an axis, gauges an object's propensity to keep spinning.

List the object's mass and speed in step one. Convert any values into SI units in step two (kg, m, s). Step 3: To calculate an object's momentum, multiply the object's mass and velocity.

Momentum can go wrong. As a vector quantity with both magnitude and direction, momentum has both. The sign, positive or negative, in physics serves as a cue as to the direction. Positive amounts normally signify a forward or upward motion, whereas negative quantities typically indicate a backward or downward motion.

The new volume of Carbon dioxide be 5.36 mL.

Boyle's Law can also be used to explain how a syringe operates. A syringe's plunger being drawn out causes the volume inside the barrel to expand, which lowers the pressure inside the barrel.

According to Boyle's Law, P1V1=P2V2 while the temperature is constant. In accordance with Boyle's Law, pressure and volume are inversely linked. In other words, volume decreases as pressure rises (and vice versa).

Given:

Volume (V1) =5ml

Pressure (P1) = 30 mmHg

Pressure (P2) =28 mmHg

Volume (V2) = ?

From Boyle's Law,

The capacity to move joints and muscles throughout their complete range of motion while engaging in active activity is known as dynamic flexibility.

The absolute range of motion that a person can acquire through movement is referred to as dynamic flexibility. In other words, the greatest range of motion is the maximum distance that may be reached, bent, or turned. The terms "dynamic flexibility" and "ballistic flexibility" are interchangeable.

Static stretches are those in which you remain in a single position—standing, sitting, or lying still—for up to 45 seconds. Dynamic stretches are regulated motions that get your ligaments, muscles, and other soft tissues ready for action and safety.

Before a workout or any sort of exercise, dynamic stretching is an excellent approach to improve flexibility and engage key muscles.

Answer:

Generally with successive half-life a new element is formed from the decayed nuclei:

isotope - daughter nucleus has same no. of protons (same atomic number) so                       the same element is formed in the decay

isotone - daughter nucleus has same number of neutrons so the atomic number has changed and a new element is formed (new atomic number)

isobar - daughter nucleus has same mass number - this could be an example of beta decay where the decayed nucleus has the same mass number but loses a neutron and gains a proton because of the lost electron and a new element is formed with the atomic number increases by 1

Example:

    U238 Uranium - alpha to Th234

    Th234 Thorium - 2 beta to U234     (back to U but atomic mass less by 4)

   U234 Uranium - alpha to Th230

The spring in a scale stretches 1 centimetres when a 5 newton object hangs from it. The required weight of an object is 10 N if it stretches the spring 2 centimetres.

Hooke's law tells us that, F = -kx

x is the distance stretched by a spring

F is the force

Length x₁ = 1 cm

Force F₁ = 5 N

Length x₂ = 2 cm

F₂ = ?

From the above equation, we can write,

F₁/x₁ = F₂/x₂

The energy transferred to the system is equal to the work done. For the endothermic process work done is negative. The power of the system is the product of work and time. Hence, the power is 315000 watt.

Endothermic reactions are those which absorbs energy into the system. Thus the surrounding temperature gets decreased.

The calorimetric equation connecting the heat transferred q, with the specific heat, mass and temperature difference is  written as:

q = m c ΔT

Here, the heat energy transferred is equal to the work done on the system. Hence W = - 1050 J

Power of the system is the product of work done and time taken for the energy transfer.

A boy weighing 40 kg jumps off a 600 kg raft horizontally. If the youngster is leaving the raft at a velocity of 4.0 m/s, the raft will be moving at a speed of 0.26 m/s.

The conservation of linear momentum is a general law of physics that states that no single item, or system of objects, experiences a change in the quantity called momentum that describes motion. Momentum is the force needed to stop an item moving at a certain speed in a given amount of time. It is calculated by multiplying an object's mass by its velocity.

Given,

mass of the boy (m₁) = 40 kg

mass of the raft (m₂) = 600 kg

speed of the boy (u₁) = 4 m/s

We have to find out the speed of the raft (u₂)

By conservation of linear momentum, We get

m₁u₁ = m₂u₂

⇒ u₂ = (m₁ ₓ u₁)/m₂

⇒ u₂ = (40*4)/600

The acceleration due to gravity at the surface of Neptune is calculated to be 10.08 m/s².

Here, we can apply the concept of Newton for the definition of the gravity of a planet, for which he defines that this is proportional to the product of the mass of the planet by the universal gravitational constant, and inversely proportional to the square of the radius of the planet. Mathematically this can be described as

g = GM/r²

where,

G is universal gravitational constant

M is the mass of the planet

r is the radius of the planet

Given that,

Mass of the planet M = 1.025 × 10²⁶ kg

Diameter of the planet = 49532 km = 49532 × 10³ m

Radius of the planet = 24766 × 10³ m

According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum. Check out Newton's laws of motion.

Momentum can be viewed as a body's "power" while it is moving, or the amount of force it can exert on another body. For instance, a baseball (small mass) thrown quickly can have the same momentum as a bowling ball (big mass) going extremely slowly (low velocity) (high velocity).

Momentum = Mass × Velocity
