A sinusoidal force with an amplitude of 1.70N drives the system = 0.641 Hz if Damping is negligible for a 0.150kg object hanging from a light, 6.30N/m spring.
What is a force in science?In science, the word 'force' has a precise meaning. At this level, it is completely appropriate to describe a force as a push or a pull. A force is not something that an object contains or 'has in it'. A force is exerted on one object by another.
What is balance force?Balanced forces: Balanced forces are those that are opposite in direction and equal in size. Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is no change in direction.

40 VA
1/(40+j30) VAR
The apparent power delivered to this load is 50VA. For a load, S = 40 + j 30 VA is the complex power. The appropriate response is option a. Power in physics is the quantity of energy transported per unit time.
The watt, which is equal to one joule per second in the International System of Units, serves as the unit of power. Power is occasionally referred to as activity in earlier writings. Energy is a scalar quantity. The precise definition of a load is as follows: Any device that allows energy to pass through it is a load. It disperses or transfers the energy to another location. The elsewhere could be the environment in the form of heat, light, flux, or another device as mechanical power or shaft energy.

A paper airplane is dropped from a balcony. what will friction from the air do to the paper airplane? speed up the airplane it will not change the airplane's speed. slow down the airplane
A paper airplane is dropped from a balcony, then the friction from the air slow down the airplane. As paper plane moves through the air, the air pushes against the airplane, hence slowing it down. This is called drag.
What is meant by drag?The force that slows the plane down as it pushes against the air it is moving through is called drag. It is a kind of friction and is also called as air resistance.
In fluid dynamics, drag is a force acting opposite to the relative motion of an object moving with respect to the surrounding fluid. Drag is non-existent, without motion.

Calculate the mass of water in the can.
HELP PLS!!!!! PHYSICS
The mass of the water in the can, temperature of the water decreased from 85.0 °C to 65.0 °C is 0.125 Kg
How do I determine the mass of the water in the can?From calorimetry, we understood that heat and mass are related according to the given formula:
Q = MCΔT
Where
Q is the heat energyM is the massC is the specific heat capacityΔT is the change in temperatureUsing the above formula, the mass of the water can be obtained as follow:
Initial temperature of water (T₁) = 85.0 °CFinal temperature of water(T₂) = 65.0 °CChange in temperature (ΔT) = 65 - 85 = -20 °C Specific heat capacity of water (C) = 4200 J/KgºC Heat transferred (Q) = -10.5 KJ = -10.5 × 1000 = -10500 JMass of water (M) =?Q = MCΔT
-10500 = M × 4200 × -20

A slab of insulating material of uniform thickness d, lying between -d/2 to +d/2 along the x axis, extends infinitely in the y and z directions. The slab has a uniform charge density rho. The electric field is zero in the middle of the slab, at x = 0.
(a) What is Eout, the magnitude of the electric field outside the slab? As implied by the fact that Eout is not given as a function of x this magnitude is constant everywhere outside the slab, not just at the surface. Express your answer in terms of d, rho, and ε_0.
(b)What is Ein, the magnitude of the electric field inside the slab as a function of x? Express your answer in terms of x, rho, and ε_0.
Answer: a) The electric field outside the slab can be calculated using Gauss's Law. Since the electric field is zero in the middle of the slab and the charge density is uniform, the electric flux through any Gaussian surface that encloses the middle of the slab will be zero. Therefore, the electric field outside the slab must also be zero.
b) Inside the slab, the electric field can be calculated using the formula for the electric field due to a uniform charge distribution: E = rho/(2*ε_0). This formula gives the electric field as a constant, independent of x. The electric field inside the slab will be uniform and directed from the negative charge towards the positive charge.

The height of mercury on the right side of the U-tube is 0 cm.
The height of mercury in the U-tube is determined by the pressure difference between the two sides of the tube. Since air is an ideal fluid, it has no viscosity and the flow rate is determined by the pressure difference.
In this case, the flow rate is the same on both sides of the tube, so the pressure difference is zero and the height of mercury on both sides of the tube is the same. Therefore, the height of mercury in the right side of the U-tube is 0 cm.

After the capacitor is fully charged, the battery is removed and the capacitor is discharged through the resistor. How much charge is on the capacitor after 1 time constant
The charge on the capacitor C that discharge through a resistor R is 0.36 times the initial charge of the capacitor.
A capacitor C discharge through a resistor R. Let Vi = voltage when the capacitor charges to Initial charge, Qi = CVi.
When time becomes 1 time constant, t=T, for voltage on discharging capacitor, we know, V = Vie−t/τ, where τ = time constant. Now,
Vf = Vi*e−t/τ, Vf =Vi* e−T/τ, Vf=Vi *e^-1 , Vf=Vi/e.
Now let Qi be the initial full charge on the capacitor.
Then Qi=1/2C*Vi , Qf=½ C*Vf ,Qf=1/2C*Vi/e , Qf=Qi/e , Qf = 0.36 Qi.
So the charge on the capacitor after 1 time constant is 0.36 times the initial fully charge of the capacitor.

A cell has a mutation that disrupts the insulin binding site of the insulin receptor.
The insulin receptor (IR) initiates downstream signalling cascades in response to insulin binding. After then, clathrin-mediated endocytosis takes place to ingest the active IR. The mechanism and control of clathrin-mediated endocytosis of IR remain poorly understood after decades of research.
When insulin binds to its receptor on a cell, what happens?When insulin binds to the insulin receptor (IR) on the cell surface, IR kinase is activated and insulin-IR complexes are first transported to clathrin-coated pits and early endosomes that contain internalised but functional insulin receptors.
One of the main causes of neonatal diabetes is insulin gene abnormalities. They may result in proinsulin misfolding and endoplasmic reticulum retention (ER). This causes an increase in ER stress, which is thought to cause beta-cell death.
