Answer:

Cyanobacteria, Anabaena and Azotobactor are called Nitrogen fixing bacteria. These bacteria change the nitrogen in the atmosphere into a form that is used by the plants to make proteins. Plants take nitrogen in the form of nitrates. The atmospheric nitrogen is first converted into ammonia after that ammonia is converted into nitrates and this nitrates use by the plants to make proteins.

They include capsular polysaccharides, extracellular proteases, endotoxin (gram-negative anaerobes), and a variety of other toxins. Capsular polysaccharides play an important role in the stimulation of abscess formation by certain anaerobes such as Bacteroides, Porphyromonas, Fusobacterium, and Prevotella!

What is the magnitude of the force exerted by the biceps fbiceps? What is the magnitude of the force exerted by the elbow felbow

Slav-nsk [51]

Answer:

The magnitude of the force exerted by the biceps $f_b_i_c_e_p_s$ is 218.38N

The magnitude of the force exerted by the elbow $f_e_l_b_o_w$ is 194.37N

Explanation:

Firstly , lets calculate the magnitude of force exerted by biceps $f_b_i_c_e_p_s$ -

Mass of the forearm=

$m_f=1.50kg$

Mass of the ball =

$m_b_a_l_l=950g$

= 0.950kg

so, weight of the forearm=

$w_f=m_f$ g

weight of the ball=

$w_b_a_l_l=m_b_a_l_l$ g

Now , balancing torque about the elbow , we have-

$F_b_i_c_e_p_s\times d_b_i_c_e_p_s= w_f\times\frac{d_b_a_l_l}{2} + w_b_a_l_l\times d_b_a_l_l$

(here , distance of the bicep is 2.50cm = 0.025m and distance of the ball is 36cm= 0.36m)

Now putting the given values in the formula -

$F_b_i_c_e_p_s\times 0.025= 0.95\times9.8\times\frac{0.36}{2} +1.50\times 0.36$

$F_b_i_c_e_p_s=218.38N$

Now, lets calculate the force exerted by elbow $F_e_l_b_o_w$ -

Balancing the vertical forces

$F_b_i_c_e_p_s=F_e_l_b_o_w+w_f+w_b_a_l_l$

$F_e_l_b_o_w = 218.38-(1.00\times9.8)-(0.95\times9.8)$

$F_e_l_b_o_w=194.37N$

Which is most like a glacier changing Earth's land

morpeh [17]

A glacier's weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial land forms.
