The formula to find the magnitude of velocity is:
▲v= ▲M/m
▲v=Velocity Change
▲M=Momentum Change
m=Mass
Plug in the information;
▲v=345/5
The answer is 69
-35 is the ans.wer.hope this hels
<span>The answer is heterogeneous mixture. A heterogeneous mixture is a combination of substances that are combined physically but not chemically. This is a mixture that is not uniform in composition. Its components can easily be separated from one another. For example, pile of soil is a heterogeneous mixture because it consists of different components.</span>
Answer:
185.95 μsec
Explanation:
Given that:
Sine wave = 
Sinusodial signal 
= 50 kHz = 
Rise time is said to be defined as the time needed for a pulse to rise from 10% - 90% of maximum rate.
∴
= 10% = 0.1 Am
=90% = 0.9 Am
Using sine wave for ; we have:
= 0.1 Am
= 0.1
= 5.7392
Using sine wave for ; we have:
= 0.9 Am
= 
= 64.158
= 
= 
Change in rise time 
= -
= 
= 
= 
since; = 50 kHz =
= 
= 1.85952 × 10⁻⁴
= 185.952 × 10⁻⁶ sec
= 185.95 μ sec
∴ The rise in time in (μ sec) for the sinosodial signal at 50 kHz = 185.95 μ sec
