C, because Ep = m*g*h, so it means it doesn't depends on the object's speed, only its mass, gravity, and height

centimeter or millimeter.

Explanation:

The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.

Length refers to how long a material is.

  • There are different units of length.
  • Smaller units that are microscopic are used to measure length dimensions that are very small
  • For example, nanometre is used to express microscopic length values.
  • Centimeters and millimeters are used for small dimensions that we can easily see.
  • Longer lengths can take the order of a yard, kilometer, miles e.t.c

A 1.80-kg monkey wrench is pivoted 0.250 m from its center of mass and allowed to swing as a physical pendulum. The period for s
Evgen [1.6K]

Answer:

(a) I (Moment of inertia)=0.0987 kgm^{2}

(b) W(Angular Speed)=2.66 \frac{rad}{s}

Explanation:

Given data

m (Monkey mass)= 1.80 kg

d=2.50 m

T (Time Period)=0.940 s

Angle= 0.400 rad

(a) I (Moment of Inertia)=?

(b) W (Angular Speed)=?

For part (a) I (Moment of Inertia)=?

Time Period Formula is given as

T=2(3.14)\sqrt{\frac{I}{mgd} }

After Simplifying we get

I=\frac{mgdT^{2} }{4*(3.14)^{2}}

I=\frac{1.8*9.8*0.25*(0.94)^{2} }{4(3.14)^{2} }

I=0.0987 kgm^{2}

For Part (b) Angular Speed

From Kinetic Energy we get

KE=\frac{1}{2}IW^{2}

Pontential Energy

PE=mgd(1-Cosa)

KE=PE

\frac{1}{2}IW^{2}=mgd(1-Cosa)

W^{2}=\frac{2mgd(1-Cosa)}{I}

W=\sqrt{\frac{2*1.8*9.8*0.25*(1-Cos(0.4)rad)}{0.0987} }

W=2.66\frac{rad}{s}

A woman pulls on a 6.00-kg crate, which in turn is connected to a 4.00-kg
djverab [1.8K]

Answer:

B. is subject to a smaller net force but same acceleration.

Explanation:

F = m*a

So because our force applied is constant from the women pulling on the rope which means the acceleration is the same on both the 4kg create and the 6kg create. The only thing that changes here is the mass of the creates, so there is more tension force between the women and the 6kg create then there is between the 4kg create and the 6kg. It takes less force to move the 4kg create therefore the tension force is less between the two creates.

Um I don't remember how to do this, help :(
Eddi Din [679]

Pressure is a measure of force per unit area:

<em>P</em> = <em>F</em>/<em>A</em>

The water exerts a pressure of 202 kPa = 202,000 Pa on the diver, who has a surface area of 1.50 m². Then the force exerted by the water is <em>F</em> such that

<em>F</em> = <em>PA</em>

<em>F</em> = (202,000 Pa) (1.50 m²)

<em>F</em> = 303,000 N = 303 kN
