Answer:

Facilitated diffusion and active transport both utilize proteins to transport substances across membranes. Differences between active transport and facilitated diffusion 1. Active transport requires an input of energy, usually ATP, while facilitated transport does not.

Does a resulting force cause acceleration? true or false?

Vesnalui [34]

True...A moving object with a zero resultant force keeps moving at the same speed and in the same direction. If the resultant force acting on an object is not zero, a stationary object begins to accelerate in the same direction as the force. A movingobject speeds up, slows down or changes direction

An electron of mass 9.11×10−31 kg leaves one end of a TV picture tube with zero initial speed and travels in a straight line to

dedylja [7]

Answer:

$F=1.509\times 10^{-16}N$

Explanation:

We have given that mass of electron $m=9.11\times 10^{-31}kg$

It is given that initial velocity u=0 m/sec

Final velocity v = $2.7\times 10^6m/sec$

Distance S = 2.2 cm = 0.022 m

According to third law of motion $v^2=u^2+2as$

$(2.7\times 10^6)^2=0^2+2\times a\times 0.022$

$a=165.68\times 10^{12}m/sec^2$

Accelerating force F is given by F = ma

So accelerating force $F=9.11\times 10^{-31}\times 165.68\times 10^{12}=1.509\times 10^{-16}N$

For an object being launched at ground level at a tilted non-zero initial velocity, is the velocity zero anywhere? are the horiz

borishaifa [10]

The correct answer No the velocity is not zero anywhere For an object being launched at ground level at a tilted non-zero initial velocity, and horizontal or vertical components of the velocity is zero at maximum height .

Because velocity is a vector (it has magnitude and direction), the overall velocity of an object can be calculated by adding the x and y components: v2 = vx2 + vy2. Meters are used to express horizontal and vertical distances (m). The horizontal velocity component (vx) describes the effect of velocity on horizontal displacement of the projectile.

The vertical velocity component (vy) describes the effect of velocity on vertical displacement of the projectile. The vertical component of a projectile's velocity is momentarily zero (vy = 0 m/s) when it reaches maximum height. The horizontal component of its velocity, however, is not zero.
