hi, Need help with triangle law of vector addition worksheet and a verifying Newtons second law worksheet?

Yuri [45]

Use Newton's second law and the free body diagram to determine the net force and acceleration of an object. In this unit, the forces acting on the object were always directed in one dimension.

The object may have been subjected to both horizontal and vertical forces but there was no single force directed both horizontally and vertically. Moreover, when free-body diagram analysis was performed, the net force was either horizontal or vertical, never both horizontal and vertical.

Times have changed and we are ready for situations involving two-dimensional forces. In this unit, we explore the effects of forces acting at an angle to the horizontal. This makes the force act in two dimensions, horizontal and vertical. In such situations, as always in situations involving one-dimensional network forces, Newton's second law applies.

According to the chart, one gram of copper and

ad-work [718]

Answer:

C) three

Explanation:

Let gram of gold required be m . Let temperature change in both be Δ t .

heat absorbed = mass x specific heat x change in temperature

for copper

heat absorbed = 1 x .385 x Δt

for gold

heat absorbed = m x .129 x Δt

m x .129 x Δt = 1 x .385 x Δt

m = 2.98

= 3 g approximately .

These types of electromagnetic waves are listed in order of increasing frequency:

xenn [34]

Answer:

B. X-rays

Explanation:

From the given choices, x-rays will have the highest energy of the given waves.

The energy of electromagnetic waves is highly dependent on their frequency and wavelength.

Electromagnetic waves with a high frequency and small wavelength will have higher energy compared to those with low frequency and high wavelength.

X-rays are one the most energetic waves on the periodic table. They have a very high frequency and low wavelength.

A family car has a mass of 1400 kg. In an accident it hits a wall and goes from a speed of 27 m/s to a standstill in 1.5 seconds

horrorfan [7]

Answer:

The force has been reduced by 8018 N

Explanation:

The impulse exerted on the car during the crash is equal to the product of the force exerted and the duration of the collision, and it is also equal to the change in momentum of the car. So we can write:

$F\Delta t = m\Delta v$
