Which of the following represents the greatest risk factor for a stroke

cupoosta [38]

The greatest risk factor, well that depends because their is quite a few risk factors. it depends where the person is having the stroke. so say someone was having a stroke in the library then you would have to move everything out of the way so they cant hurt themselves and call the ambulance straight away and tell them the signs the person is showing to tell you their having a stroke e.g. face dropping, slowed speech and cant hold their arm up in the air on their own.

An electron is accelerated through 2.40×10³V from rest and then enters a uniform 1.70-T magnetic field. What are(b) the minimum

Korolek [52]

The maximum value of Force is 7.88x $10^{-12}$

The minimum value of magnetic force is 0

Potential V=2.40x $10^{3}$ .

Magnetic field = B = 1.70 T.

we need to find

a) The maximum value of Force

Since the particle is moving from rest, the potential energy change is 2.40x $10^{3}$ ?

Potential Energy= vq= 2,40x $10^{3}$ x (-1.6 x 10x $10^{-19}$ %).

= -8.84x $10^{-16}$

Now this will be equal to 1/2 mv²

= 1/2 mv²= 8.84x $10^{-16}$ .

v=2.903x $10^{7}$ m/s :

Wow Fmax = qvb

=1.6x $10^{-19}$ x2.903x $10^{7}$ x1.70 .

=7.88x $10^{-12}$

b) The minimum value of magnetic force

The minimum Value of magnetic force will be

when sinθ=0

The minimum value is 0

A 56 kg boat that is 7.6 m in length is initially 7.6 m from the pier. A 39 kg child stands at the end of the boat closest to th

svlad2 [7]

Answer:

Explanation:

Given

mass of boat $M=56\ kg$

mass of Person $m=39\ kg$

Length of boat $L=7.6\ m$

Center of mass of boat and child

$x_{cm}=\frac{M\times 0.5L+m\times L}{M+m}$

$x_{cm}=\frac{56\times 0.5\times 7.6+39\times 7.6}{56+39}$

$x_{cm}=\frac{509.2}{95}$

$x_{cm}=5.36---1$

when child reaches another end of boat, boat is shifted by x cm

Center of mass of the system will remain the same

$x'_{cm}=\frac{M\times (x+0.5L)+m\times x}{M+m}$

$x'_{cm}=\frac{56\times (x+0.5\times 7.6)+39\times x}{56+39}----2$

Equating 1 and 2 we get

$509.2=95x+212.8$

$x=3.12\ m$

Alekssandra [29.7K]

Answer:

2.92682 m

$1.5\times 10^{18}\ Hz$

250000000000 Hz

$2.88462\times 10^{-8}\ m$

0.21126 m

0.12244 m

Explanation:

c = Speed of light = $3\times 10^8\ m/s$

$\lambda$ = Wavelength

f = Frequency

Wavelength is given by

$\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{102.5\times 10^6}\\\Rightarrow \lambda=2.92682\ m$

The wavelength is 2.92682 m

Frequency is given by

$f=\dfrac{c}{\lambda}\\\Rightarrow f=\dfrac{3\times 10^8}{0.2\times 10^{-9}}\\\Rightarrow f=1.5\times 10^{18}\ Hz$

The frequency is $1.5\times 10^{18}\ Hz$

$f=\dfrac{c}{\lambda}\\\Rightarrow f=\dfrac{3\times 10^8}{1.2\times 10^{-3}}\\\Rightarrow f=250000000000\ Hz$

The frequency is 250000000000 Hz

$\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{1.04\times 10^{16}}\\\Rightarrow \lambda=2.88462\times 10^{-8}\ m$

The wavelength is $2.88462\times 10^{-8}\ m$

$\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{1.42\times 10^{9}}\\\Rightarrow \lambda=0.21126\ m$

The wavelength is 0.21126 m

$\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{2.45\times 10^9}\\\Rightarrow \lambda=0.12244\ m$

The wavelength is 0.12244 m
