True or False A Safety Data Sheet (SDS) provides even more information on chemicals than a label.

Sonja [21]

A Safety Data Sheet (SDS) provides even more information on chemicals than a label: True.

<h3>What is a Safety Data Sheet (SDS)?</h3>

A Safety Data Sheet (SDS) can be defined as a text-based document (bulletin) that is developed to provide more information with respect to the chemical and physical properties of a chemical compound, substance or equipment such as:

Flammability

Temperature

Radioactivity

Additionally, a Safety Data Sheet (SDS) contains information on the potential health hazards and safety precautions for proper use, handling, storage and transportation of a chemical compound, substance or equipment.

In conclusion, we can deduce that a Safety Data Sheet (SDS) provides even more information on chemicals than a label, which only contains lesser information about a product.

otez555 [7]

Answer:

Height reached will be 28.35 m

Explanation:

Here we can use the work energy theorem to find the maximum height

As we know by work energy theorem

Work done by gravity + work done by friction = change in kinetic energy

$-mgh - F_f h = 0 - \frac{1}{2}mv_i^2$

now we will have

$-1.60(9.8)(h) - 0.900(h) = - 470$

$-16.58 h = -470$

$h = 28.35 m$

so here the height raised by the stone will be 28.35 m from the ground after projection in upward direction

The total work done is equal to 134 J.

The work formula is characterized as the multiplication of the force performed and the distance in which the movement was performed, so that:

$W = F \times d$

Thus, it is enough to calculate the value of the work in each movement and add to find the total work, so that:

$W_1 = 3 \times 28 = 84J\\W_2= 4 \times 14 = 56J\\W_3 = (-1.2) \times 5 = 6J$

$84 + 56 + (-6) = 134J$

So, the total work done is equal to 134 J.

A police car is driving north with a siren making a frequency of 1038 hz. Moops is driving north behind the police car at 12 m/s

Marianna [84]

Answer:

The police car is moving at 41.24 m/s.

Explanation:

To find the speed of the police car we need to use the Doppler equation:

$f = f_{0}(\frac{v + v_{r}}{v + v_{s}})$

Where:

v: is the speed of the sound = 343 m/s

$v_{r}$ : is the speed of the receiver = 12 m/s

$v_{s}$ : is the speed of the source =?

f: is the observed frequency = 959 Hz

f₀: is the emitted frequency = 1038 Hz

Both terms are positive in the fraction because the velocity of the sound is in the opposite direction to both velocities of the police car and the other car.

By solving the above equation for $v_{s}$ we have:

$v_{s} = \frac{f_{0}(v + v_{r})}{f} - v = \frac{1038(343 + 12)}{959} - 343 = 41.24 m/s$

Therefore, the police car is moving at 41.24 m/s.

I hope it helps you!
