What is the electric field strenght in units of N/C if the flux through a 2.0m by 1.0m rectangular surface is 396Nm2/C, if the electric field is uniform, and if the plane of the surface is at an angle of π/3 radians with respect to the direction of the field ?
Answer:
The appropriate answer is "396 N/C".
Explanation:
The give values are:
Rectangular surface,
[tex]\Phi_e=396 \ N.m^2/C[/tex]
[tex]a = 2 \ m[/tex]
[tex]b = 1 \ m[/tex]
Angle,
[tex]\theta =\frac{\pi}{3} \ radian[/tex]
Now,
The area of rectangle (A) will be:
= [tex]a\times b[/tex]
= [tex]2\times 1[/tex]
= [tex]2 \ m^2[/tex]
hence,
The electric field strength will be:
⇒ [tex]\Phi_e=E.A Cos \theta[/tex]
or,
⇒ [tex]E=\frac{\Phi_e}{ACos \theta}[/tex]
On putting the given values, we get
⇒ [tex]=\frac{396}{2\times Cos(\frac{\pi}{3} )}[/tex]
⇒ [tex]=\frac{396}{2\times 0.5}[/tex]
⇒ [tex]=\frac{396}{1}[/tex]
⇒ [tex]=396 \ N/C[/tex]
The water hyacinth lives in lakes and ponds it forms large floating mats of plants because it does not root in soil which adaptation lets it get nutrients directly from the water is it A.1 curly leaves B.Trailing C.Sturdy stems D. Upright flowers
Answer:
C. Sturdy stems
Explanation:
Sturdy stems is the adaptation that enables water hyacinth to get nutrients directly from the water because there is no roots are present for the absorption of nutrients from water. The hollow bulbous stem below each leaf of water hyacinth allows the plant to get nutrients from the water. This hollow bulbous stem allow the plants to float on the water surface, keeping the leaves and flowers above the water so they don't rot.

explain why does the bowling ball decelerate as it travels along the lane
The main cause of this is Friction. The more oil that is laid down, the less friction there is between the ball and the lane surface. The less friction, the harder it is for the bowler to send the ball in a curved path imparted by the spin that the bowler puts on the ball at the instant of release.

No matter how well we get along with our parents as adolescents, there comes a time when we need to break away and assert our own independence. There are several ways in which we do this, some of them deliberate and intentional and some of them not so intentional. Describe several ways you use or have used to break away from your parents. Briefly describe your parents' reactions.
Answer: I never said anything to them but if i did it would be "I need a break from you, i love you but sometimes I have to find the path on my own." i would say this if i wasn't scared to hurt them.

Which type of uninterruptible power supply uses AC power to continuously charge its battery, while also providing power to devices through the battery?
Answer:
An online UPS.
Explanation:
An online UPS is a type of uninterruptible power supply uses AC power to continuously charge its battery, while also providing power to devices through the battery. It combines the inverter and rectifier to provide power to the alternating current (AC) load while supplying alternating current (AC) power during an outage to the load through the inverter.
Basically, an uninterruptible power supply unit is used to provide constant power supply to an electrical device, especially during a power outage.

Cold packs are designed to become very cold when activated. When the pack is activated, a chemical reaction occurs to make the temperature of the cold pack decrease. What must be true of this chemical reaction? (2 points) The reaction releases energy to its surroundings. The reaction releases energy to its surroundings. The products and reactants have the same amount of energy. The products and reactants have the same amount of energy. The products have less energy than the reactants. The products have less energy than the reactants. The reaction absorbs energy from its surroundings.
Answer:
The reaction absorbs energy from its surroundings.
Explanation:
An endothermic reaction is any reaction in which energy is absorbed by the reaction system.Thus implies that energy is withdrawn from the environment A cold pack's function is based on an endothermic chemical reaction.
The absorption of energy by the reaction system means that the environment feels cool in an endothermic reaction.This manifests in a decrease in the temperature of the cold pack.

Two bears sit on a see-saw. The see-saw is 3.5 m in total
length with the fulcrum at the center. A 40 kg baby bear sits at the very end of one side. Where should the 120 kg father bear sit relative to the center to keep the see-saw balanced?
Answer:
Explanation:
For the see-saw to be balanced, take moment at the fulcrum:
40g * 3.5/2 = 120g * distance
distance = 1.167m from the center

A body is thrown up with with velocity u.it reaches maximum height h. If velocity of projection is doubled the maximum height is..
Answer: 4h
Explanation:
Given
The body is thrown vertically upward with velocity u and reaches a height of h
The relation between u and h is given by
[tex]\Rightarrow v^2-u^2=2as\\[/tex]
Put [tex]v=0,a=-g[/tex] in above equation
[tex]\Rightarrow 0-u^2=2(-g)h\\\\\Rightarrow h=\dfrac{u^2}{2g}[/tex]
If the velocity of projection is doubled i.e. 2u
[tex]\Rightarrow h'=\dfrac{(2u)^2}{2g}\\\Rightarrow h'=4\times \dfrac{u^2}{2g}\\\\\Rightarrow h'=4h[/tex]
The maximum height becomes 4h
A satellite is acted upon by a 10n force upwards and 20n force downwards. What is the net force acting on the satellite and what direction will it move in
Answer:
Net force = 10 N in downward direction
Explanation:
Given that,
Upward force = 10 N
Downward force = 20 N
Let downward is negative and upward is positive.
Net force = 10+(-20)
= -10 N
So, the net force is 20 N and it is acting in downward direction.

Two students go to play basketball. They notice the ball is flat (it won't bounce). They decide to pump it up with air. After it is pumped with air, will the ball have more, less, or the same amount of mass as before air was added?
A. The ball has less mass after being pumped with air.
B.Cannot determine unless we measure the mass.
C.The ball has more mass after being pumped with air.
D. The ball has the same amount of mass after being pumped with air.
Justify your answer
The ball has more mass being pumped with air. So, option (C) is correct answer.
What is mass?In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has. The kilogram serves as the unit of mass in the International System of Units (SI).
As the amount of air is added to the basketball by pumping it up with air, the mass of air is also added with the basketball. Hence, the ball has more mass now.
