Answer:

The velocity of the release is 4.9 m/s.

Explanation:

Susan catches the dough, at the point of the release only therefore, the displacement of the piece of dough is 0 and the total time elapsed is 1s.

The gravity exerted will be only due to gravity as air resistance is neglected, so lets' assign downwards direction as negative and the gravity will come out to be -g.

We have to apply Second Equation of Motion which states that,

s=ut+\frac{1}{2} at^{2}

s=0

t=1

a=-g=-9.8

u=??

Plugging in the values, we get

0=u-4.9

u=4.9 m/s

Therefore, the velocity of the release is 4.9 m/s

With what force will a car hit a tree if the car has a mass of 3,550 kg and it is accelerating at a rate of 2.5 m/s2 on a snowy
bekas [8.4K]

Answer:

<h2>8875 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 3550 × 2.5

We have the final answer as

<h3>8875 N</h3>

Part A: Explain why x = 5 makes 4x − 1 ≤ 19 true but not 4x − 1 &lt; 19. (5 points) Part B: What value from the set {6, 7, 8, 9,
Elis [28]

Answer:

A: ≤ means less than OR equal to. < only means less than

B: 9

Explanation:

A: Because it would equal 19, and 19 is EQUAL than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.

B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.

Hope this helps <3

In a digital multimeter, what changes inside the meter when you push the button to change from 200v range to the 20v range? by w
charle [14.2K]
So we want to know what changes inside the multimeter when we change the voltage range from 200 V to  20 V, by what factor and does it increase or decrease. What we want when trying to measure the voltage with a multimeter is that a minimal current passes trough the mulitmeter so when we change the voltage range, we decrease the resistance by a factor of 10 because the voltage is decreased by a factor of 10.
